Abstract

1279669 Ethylene-unsaturated silane copolymers BADISCHE ANILIN- & SODA-FABRIK AG 19 Nov 1969 [20 Nov 1968] 56626/69 Heading C3P Copolymers of 100 parts by weight ethylene units, 0À1 to 35 parts by weight of units of one or more unsaturated silanes CH 2 = CHSiR 1 R 2 R 3 or CH 2 = CHCH 2 SiR 1 R 2 R 3 where R 1 , R 2 and R 3 are H, C 1-12 alkyl, benzyl or tolyl and optionally up to 25 parts by weight of units of one or more further ethylenically unsaturated compounds, are prepared by copolymerization at 80‹ to 350‹ C. and 500 to 5000 atmospheres in the presence of a free radical polymerization initiator and optionally a polymerization regulator. Specified comonomers are vinyl alkanoates, acrylic and methacrylic esters, and acrylic, methacrylic, maleic and fumaric acids and amides. The initiator may be oxygen, and the regulator propylene. Examples describe the copolymerization of ethylene with (1) vinyl trimethyl silane in the presence of propylene and (2) allyl dimethyl silane, using oxygen as initiator.
