Rubbery polymer composition
Abstract
Abstract A rubbery polymer composition comprises a crosslinked copolymer comprising the following components. Type I 15 to 40 wt. parts of a vinyl carboxylate having the formula (I); 60 to 85 wt. parts of an alkoxyalkyl acrylate having the formula (II); 0 to 15 wt. parts of ethylene; (100 wt. parts of a total of said three components); 0 to 5 wt. parts of the components having the formula (III), (IV) or (V): Type II 15 to 55 wt. parts of a vinyl carboxylate having the formula (I); 5 to 20 wt. parts of ethylene; an alkyl acrylate having the formula (II'); an alkoxyalkyl acrylate having the formula (II) (100 wt. parts of a total of said four components and more than 0.8 of a ratio of the alkoxyalkyl acrylate (II) to the alkyl acrylate (II') by weight); 0 to 5 wt. parts of the components having the formula (III), (IV) or (V): RCOO--CH═CH.sub.2 (I) wherein R represents a C 1-4 alkyl group. CH.sub.2 ═CHCOO--R.sub.1 --O--R.sub.2 (II) wherein R 1 represents a C 1-4 alkylene group; and R 2 represents a C 1-4 alkyl or alkoxyalkyl group. CH.sub.2 ═CHCOO--R.sub.6 (II') wherein R 6 represents a C 3-8 alkyl group. ##STR1## wherein R 3 represents hydrogen atom or methyl group. ##STR2## wherein R 4 represents vinyl, allyl or methallyl group. CH.sub.2 ═CH--O--R.sub.5 (V) wherein R 5 represents CH 2 Cl--CH 2 --or CH 2 Cl--CO--group.
