Abstract:
Compositions containing polymers and one or more heat labile and/or incompatible components adsorbed on carrier materials are provided. The heat labile components include materials that are inactivated, that volatilize, decompose, or undergo a chemical reaction or transformation at the polymer's processing temperatures (heat labile biocides). Incompatible components are materials that generally react or form gels or precipitates upon mixing. The carrier materials generally include inorganic or organic porous materials capable of remaining solid during processing temperatures. Methods for preparing the polymer compositions are provided.
Abstract:
Described are wrought forms of copper alloys (20) for infiltrating powder metal parts (1), the method for preparing the copper alloys and their wrought forms, the method for their infiltration into a powder metal part, and the infiltrated metal part infiltrated with the novel alloys having a generally uniform distribution throughout and exhibiting high transverse rupture strength, tensile strength and yield strength. Infiltrated metal parts prepared by infiltrating powder metal parts with reduced amounts of the novel infiltrant typically weigh less and have superior strengths compared to similarly prepared infiltrated metal parts prepared with standard methods and conventional infiltration.
Abstract:
Described are preferred processes for preparing substituted pyridines by the reaction of a pyridine with nitric acid, an anhydride and optionally a nucleophile. Preferred processes yield cyanopyridines, pyridyl ketones, substituted nitroalky pyridines, and nitropyridines depending on the starting material chosen, whether a nucleophile is utilized and whether the nucleophile is a source of cyanide ion.
Abstract:
Biodegradable graft copolymers derived from a carbohydrate, including nitrogen- containing carbohydrates and modified carbohydrates, and at least one α,β-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available stirred and/or continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying.
Abstract:
The present invention relates to the technical field of providing corrosion resistant coatings or anticorrosion coatings on substrates which are susceptible to corrosion, particularly on metallic substrates, especially of providing chromate-free corrosion resistant (anticorrosion) coatings on such substrates.
Abstract:
Resist stripping agents, useful for fabricating circuits and/or forming electrodes on semiconductor devices for semiconductor integrated circuits with reduced metal etch rates, particularly copper etch rates, are provided with methods for their use. The preferred stripping agents contain low concentrations of a copper or cobalt salt with or without an added amine to improve solubility of the copper or cobalt salt. Further provided are integrated circuit devices and electronic interconnect structures prepared according to these methods.
Abstract:
This disclosure relates to a family of micronutrient supplements that can be used in food or in animal feeds and to methods of enhancing the growth of animals using one or more of the supplements. The family of micronutrient supplements is an ammine chloride salt of an essential metal. Representative essential metals for use according to this disclosure include a divalent or trivalent cation of zinc, copper, manganese, magnesium, chrome, iron, cobalt and calcium. When provided as a metal ammine chloride salt, the essential metal is highly bioavailable to enhance the survivability, growth, health and/or reproductivity of animals. The micronutrient supplement can be administered to animals either as a single supplement or admixed with other nutrients or feeds.
Abstract:
The present invention relates to a method of manufacturing a cellulosic film (cellulose film), particularly a cellulosic food packing film, especially a detectable cellulosic film, which cellulosic film comprises detectable particles incorporated therein, as well as to the cellulosic film thus produced and to its applications and usages (i.e. its use).
Abstract:
Surfaces and members having one or more surfaces derived from compositions containing polymers and one or more heat labile and/or incompatible components adsorbed on carrier materials are provided. The heat labile components include materials that, unless adsorbed on a carrier, are transformed at the polymer's processing temperatures (such as for example, heat labile biocides). Incompatible components are materials that generally react or form gels, slimes or precipitates upon mixing. The carrier materials typically include inorganic and/or organic porous materials capable of remaining solid during processing temperatures. Methods for preparing the polymer surfaces and members having polymer surfaces are provided. Members include, but are not limited to, structures, articles, containers, devices, woven/nonwoven articles, remediation materials, and the like.
Abstract:
An integrated lean bum stabilizer (ILBS) for initiating combustion in an internal combustion engine by generating and introducing active free radicals into a combustion chamber is provided. Engines equipped with the ILBS can achieve a fuel efficient clean combustion processes with a lean and/or diluted mixture otherwise incapable of auto ignition and provide a controlled start of combustion, in conjunction with early in-cylinder direct injection, late diesel-like in-cylinder direct injection, and mixed fuel functions allowing control of the composition and stratification of the mixture. Controlled aspects of the fuel mixture include the equivalent ratio and fuel reactivity combinations inside the main combustion chamber.
