1449873 Anti-tack composition NEYNABER CHEMIE GmbH 10 Dec 1973 [20 Dec 1972] 57066/73 Headings C3P and C3R Tackiness during shaping of a thermoplastics mass is prevented by mixing with 0À01-5% wt., based on the mixture, of a lubricant-antitack composition comprising a mixed ester (A) with OH or acid value 0-6, and ester(s) (B) in which the wt. ratio (A)/(B) is from 1/3 to 9; where (A) is formed from (a) an aliphatic, cycloaliphatic, or aromatic dicarboxylic acid, (b) an aliphatic polyol, and (c) a C 12-30 aliphatic monocarboxylic acid, and (B) is formed from (1) C 12-30 monofunctional aliphatic alochol + dicarboxylic acid, (2) C 12-30 monofunctional aliphatic alcohol + C 12-30 aliphatic monocarboxylic acid, or (3) aliphatic polyol + C 12-30 aliphatic carboxylic acid, (3) being a complete partial ester. The thermoplastic compound may be vinyl chloride, vinylidene chloride, or styrene polymer or copolymer, or poly(meth)acrylate, polyamide, or polyurethane.
