Abstract: Reaction products of maleic anhydride and/or itaconic anhydride with one or more olefinically-unsaturated fatty compounds as compatibilizers for cellulose/plastic composites.

Abstract: A process for the production of cellulose/plastic composites, characterized in that cellulose, more particularly wood, a plastic, more particularly polyvinyl chloride, a compatibilizer containing carboxylic anhydride groups, and a catalyst from the group of heteroaromatic compounds are combined, mixed together, preferably at a temperature in the range from 50° to 130° C., and the dry blend obtained is subsequently heated to a temperature above the melting temperature of the plastic, subjected to the desired shaping process, and allowed to cool.

Abstract: A dust-free stabilizer additive for use in plastics, the additive comprising agglomerates containing: (a) a plurality of stabilizer composition particles; and (b) a binder composition encapsulating the stabilizer composition, the binder composition containing at least one binder component having a melting point lower than a melting point of the stabilizer composition particles.

Abstract: Compositions and processes for the aqueous emulsion polymerization of ethylenically unsaturated monomers using mixed emulsifiers containing(a) about 99.5 to about 10 parts by weight of an .alpha.-sulfocarboxylic acid alkyl ester containing from 8 to 24 carbon atoms in the carboxylic acid portion and from 1 to 4 carbon atoms in the alcohol portion, and(b) from about 0.5 to about 90 parts by weight of an .alpha.-sulfocarboxylic acid containing from 8 to 24 carbon atoms, and if desired,other anionic and/or non-anionic emulsifiers and/or protective colloids; the mixed emulsifier optionally being completely or partly present in salt form.

Abstract: Bis-semiesters of sulfosuccinic acid with polyether diols based on ethylene oxide/propylene oxide and/or their alkali metal and/or ammonium salts as surfactants, i.e., agents for reducing the surface tension of aqueous substrates such as water or aqueous solutions, as dispersants, wetting agents and leveling agents. Another aspect of the invention relates to the use of such bis-semiesters and/or such salts as emulsifiers in the emulsion polymerization of water insoluble monomers.
