Abstract: The invention relates to modified plastics characterized in that they contain adhesion-reducing substances in such a quantity that the adhesion of microorganisms to their surface is lower by at least 50% than for non-modified plastics, and in that they contain biocidal substances in such a quantity that at least 60% of the microorganisms remaining are destroyed within 24 hours.

Abstract: A polyvinyl alcohol having at least 1.9 mol % of 1,2-glycol bonds is used as a dispersant for emulsion polymerization or a dispersant for suspension polymerization, and this ensures good polymerization stability even when its amount used is reduced. The aqueous emulsion comprising the polyvinyl alcohol is resistant to water and the viscosity of the aqueous emulsion depends little on ambient temperatures. The vinylic polymers obtained through suspension polymerization in the presence of the polyvinyl alcohol are yellowed little, and the waste water in the suspension polymerization pollutes little the environment.

Abstract: 2H-Benzotriazole UV absorbers substituted at the 3-position or at the 5-position of the phenyl ring by a 1,1-diphenylalkyl moiety, particularly a 1,1-diphenylethyl group, are particularly photostable in automotive coatings, and are of low color and exhibit low volatility in thermoplastic compositions.

Abstract: The present invention relates to surfactantless latex compositions. More particularly, the present invention pertains to surfactantless latex compositions comprising sulfo-polyester polymers wherein the compositions have a continuous phase comprising water, diol, polyol or a mixture thereof. Still further, the present invention provides methods of making polymer blends comprising a condensation polymer and a latex polymer whereby the latex polymer is derived from a surfactantless latex composition comprising sulfo-polyester polymers. Polymer blends made by such methods are also provided.

Abstract: The present invention relates to aqueous formulations comprising: i. at least one hydrophilic particulate polymer P1, as an aqueous dispersion, composed essentially of monoethylenically unsaturated monomers having a water-solubility in the range from 10 to 100 g/l (at 25° C. and 1 bar), and ii. at least one hydrophobic particulate polymer P2, as an aqueous dispersion, composed essentially of ethylenically unsaturated monomers having a water-solubility below 10 g/l (at 25° C. and 1 bar), the glass transition temperature Tg1 of the polymer P1 being less than 10 K different from the glass transition temperature Tg2 of the polymer P2.

Abstract: A pressure sensitive hot melt adhesive composition which comprises a high molecular weight rubber and less than about 60 parts by weight of a liquid diluent, and has a G′ of less than about 15×104 dynes/cm2 at 10 rad/s at 25° C. is useful for adhesive skin application (e.g., surgical tape), including transdermal drug delivery applications.
