    Abstract: 1,125,571. Polyethylene compositions. BADISCHE ANILIN & SODA FABRIK A.G. 21 Jan., 1965 [13 Jan., 1965], No. 1387/66. Heading C3P. Moulding materials are prepared by a process which comprises incorporating a concentrate of carbon black in an ethylene/ethylenically unsaturated carboxylic ester copolymer into polyethylene. The copolymer may be of ethylene with vinyl acetate, propionate or stearate, C 1-4 alkyl acrylates or methacrylates, or diethyl maleate.. The concentrate may be stabilized, e.g. with organic sulphur compounds, and may be incorporated by conventional mixing apparatus or added to a stream of molten polyethylene. Examples describe the incorporation in polyethylene of concentrates of carbon black in (1) ethylene/vinyl acetate copolymer, (2) ethylene/ethyl acrylate copolymer, (3) ethylene/ n-butyl acrylate copolymer, (4) ethylene/t.-butyl acrylate copolymer, and (5) a mixture of ethylene/vinyl acetate copolymer and ethylene/nbutyl acrylate copolymer.
