摘要： An additive that is used in conjunction with certain dibenzylidene sorbitol-type (DBS) clarifiers and acid scavengers within polyolefin resins to reduce the release of aldehydes from polypropylene material is disclosed. Hydrazides have been shown to be effective at removing residual aldehyde from polyolefins, such as polypropylene. This function can be accomplished with a minimal impact on optical transparent properties imparted to the polypropylene by the clarifying agent. The net effect is an improvement in the organoleptic performance of resins containing clarifiers, and a reduction in the UV-absorbing extractables. Particularly, adipic dihydrazide, when co-compounded into polypropylene homopolymer with 4-methyl DBS, improves the organoleptic performance of the clarifier. Incorporation of dihydrazides into polypropylene pellets reduced air-released aldehyde by nearly 100%.

摘要： This invention relates to a process for preparing alditol acetals, such as dibenzylidene sorbitols, monobenzylidene sorbitols, and the like, through the reaction of unsubstituted or substituted benzaldehydes with alditols (such as sorbitol, xylitol, and ribitol) in the presence of a mineral acid and at least one surfactant having at least one pendant group of 6 carbon chains in length. Such a reaction provides a cost-effective, relatively safe procedure that provides excellent high yields of alditol acetal product. Furthermore, such a specific reaction is also the best known procedure for the production of certain compounds which can be easily separated from other formed isomers. Additionally, such a procedure facilitates the production of certain asymmetric alditol acetal compounds and compositions in acceptable yields as well. Such alditol acetals are useful as nucleating and clarifying agents for polyolefin formulations and articles, as one example.

摘要： Novel condensation reactions used to produce 1,3-cyclohexadiene. Such a compound is an important precursor in the manufacture of high performance plastics, as one example, are provided. In the past, the production methods for such 1,3-cyclohexadiene required very complex reactions involving numerous process steps. Such a method has proven costly, difficult to properly monitor and control, and less than reliable to provide even low amounts of such a precursor compound. The inventive production methods thus permit a reduction in complexity and cost, and, with a single reaction step, facilitate quality measurements as to the product purity itself.

摘要： This invention relates to a process for preparing specific substituted benzaldehydes through the reaction of substituted benzenes with carbon monoxide and aluminum chloride at a relatively low pressure, at a low temperature, and in the presence of at most a catalytic amount of an acid (preferably aqueous HCl). The resultant substituted benzaldehydes are useful as precursors to the formation of a number of different compounds, such as dyestuffs, flavorings, fragrances, nucleating agents, polymer additives, and the like. The inventive method provides a very cost-effective and safe procedure for producing such substituted benzaldehydes at very high yields.

摘要： Ethylene-propylene diene monomer (EPDM) rubber-containing articles that exhibit highly desirable long-term effective antimicrobial characteristics are provided. Such articles are in either solid or blown (foam or sponge) state (or combinations of both in multilayered forms) that can be utilized in a variety of different applications. As silver-based compounds are deleteriously affected by utilization of standard curing agents and curing accelerators, such as sulfur-based compounds and/or systems, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult. However, this invention encompasses the presence of different non-sulfur-based curing systems and agents, such as peroxides, as one example, that permit vulcanization and do not irreversibly bind silver ions thereto, thereby resulting in long-term antimicrobial performance of the ultimate rubber article itself. The rubber articles must also comprise fillers and may also include plasticizers to provide desired characteristics of dimensional stability, stiffness, flexural modulus, tensile strength, abrasion resistance, elongation, and the like, for the ultimate rubber article, while simultaneously and surprisingly enhancing the control of antimicrobial efficacy of the rubber article as well.

摘要： Floor covering products, such as carpets, carpet tiles, floor mats, and the like, which comprise very specific antimicrobial adhesive latex formulations therein are provided. Such formulations comprise, as the only antimicrobial active ingredients, certain inorganic antimicrobial compounds, such as, preferably, silver-containing ion-exchange, glass, and/or zeolite compounds. Such latexes exhibit excellent adhesive and antimicrobial qualities and, since they do not contain any added organic bactericides (and thus no bactericide VOCs), do not release any such organic bactericides upon exposure to high processing temperatures.

摘要： Broadly defined adhesive latex formula s exhibiting antimicrobial properties. Such formulations comprise certain antimicrobial compounds, such as, preferably, metal-containing ion-exchange and/or zeolite compounds, are provided. The inventive latex formulations must also exhibit substantially uniform characteristics (such a similar viscosity and/or appearance throughout) in order to provide a functionally and aestheticially pleasing formulation for utilization within any number of applications. In order to provide such an inventive latex formulation, it has been found that compounding of all the base ingredients (polymer, antimicrobial agent, fillers) must be undertaken prior to the final thickening step, which ultimately produces the desired latex. The specific method of producing such formulations is also encompassed within this invention.

摘要： This disclosure generally pertains to a method for manufacturing a distributed optical fiber scrim comprising a functional optical fiber, the functional optical fiber scrim thus manufactured, and composites in which an optical fiber scrim is incorporated. The present disclosure describes a variety of textile scrims, particularly adhesively bonded nonwoven scrim materials, each comprising at least one optical fiber with a continuous path across at least the length or width of the fabric. Such optical fiber scrims may be useful as sensor components (for example, as a detector of breakage, strain, pressure, or torque), as illumination components (for example, in a variety of light-providing applications), or as data-distribution components, either alone or in combination with other materials, such as fabrics, films, foams, and the like.

摘要： This invention relates to improvements in inhibiting undesirable discoloring of plastic articles within which silver-based antimicrobials have been introduced. Such a method requires the utilization of very low amounts of acid scavengers or stabilizers such as aluminum-magnesium hydroxycarbonate, otherwise known as hydrotalcite (and not a zinc-based compound). Such hydrotalcites are very low in cost, easy to handle, and, utilized in very low levels in combination with a silver-based antimicrobial within a plastic composition, surprisingly substantially prohibits the generation of unwanted aesthetically displeasing colors.

摘要： This invention relates to antireflective coatings comprising polymeric polyoxyalkylenated colorants. More particularly, the present invention relates to antireflective coatings for utilization in forming thin layers between reflective substrates and photoresist coatings. Such antireflective coatings are very useful and beneficial within the production and fabrication of semiconductors through photolithographic procedures due to the liquid, non-crystallizing nature of polyoxyalkylenated colorants, and the lack of potentially damaging counterions, metals, and/or electrolytes within the inventive antireflective colored coatings. The inventive coatings may also be applied on lenses, mirrors, and other optical components. Methods of forming such antireflective coatings are also contemplated within this invention.
