摘要:
Compositions that include polymer and silane can be used in various finish compositions, especially finish compositions intended for use on hard, high gloss surfaces. The silane of the composition can be in the form of a silane group attached to a polymer backbone or as a distinct component. The polymer can be provided as an aqueous emulsion or suspension in a liquid. The polymer finish composition can be used as a floor care coating or as an architectural coating such as a paint or wood finish.
摘要:
A latex binder for a pigmented paper coating, the latex including particles of an emulsion copolymer comprising (i) from about 15 to about 35 weight % mer units deriving from the polymerization of acrylonitrile; (ii) from about 25 to about 65 weight % mer units deriving from the polymerization of conjugated diene monomer; and (iii) from about 5 to about 55 weight % mer units deriving from the polymerization of alkenyl aromatic monomer, based upon the total weight of the mer units within the particle.
摘要:
The invention provides a film that includes chloride-containing vinyl polymer and a stabilizer component, wherein the film has a 96-hour Volatile Organic Compound Emission Factor of no more than 1,000 µg/m2/hour. The invention also provides a film that includes vinyl chloride polymer and a stabilizer component comprising a stabilizer and a diluent, wherein the diluent comprises a monohydric alcohol having 12 or more carbon atoms. Also described are methods of stabilizing a chloride-containing vinyl polymer film, a system for providing a low VOC releasing chloride containing vinyl polymer film, and methods of printing a chloride-containing vinyl polymer film.
摘要:
An article is produced from a mold such that it includes a barrier so as to prevent a coating composition applied thereto while it remains in the mold from flowing into a gate pin assembly or substrate injection inlet area of the mold. The barrier prevents cross contamination between the coating composition and resin contained in the inlet area.

The invention relates to polymeric latexes that can be used in adhesive compositions, which provide improved bonding of rubber articles to rubber reinforcing articles. The adhesive composition includes a single or a blend of polymeric latexes comprising a conjugated aliphatic monomer, a vinylaromatic monomer, a vinylpyridine monomer, and a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality. Use of the monomer comprising a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality allows for reduced amounts of the vinylpyridine monomer in the latex, and enhances the bonding properties of the adhesive composition. Use of the adhesive composition provides economic and chemical advantages for the preparation of reinforced rubberized articles.
摘要:
A method of forming an organic polymeric particle, comprising (i) forming a core of an organic hydrophilic polymer with monomers that contains an acid group, a latent acid group, or a combination thereof; (ii) forming a shell that comprises an organic polymer with monomers that contains an acid group, a latent acid group, or a combination thereof to encapsulate the core, where the shell has an initial size; expanding the core to form a hollow porous structure from the shell, where the hollow porous structure has an expanded size larger than an initial size of the shell; and (iii) hydrolyzing the acid group, the latent acid group or the combination thereof of the hollow porous structure and the organic hydrophilic polymer to give the organic polymeric particle a void volume fraction of 40 percent to 85 percent.
摘要:
A method of modifying an existing injection molding system so that the system can produce articles wherein at least one of the surfaces is coated while the article remains in the mold. The method includes the steps of providing a dispensing system for a coating composition and modifying an injection molding system to communicate with the dispensing system. The modification can include at least one nozzle to inject and direct the coating composition onto at least one surface of the molded article.
