Abstract
A rubbery polymer composition comprises a crosslinked copolymer comprising the following components. PA0 Type I PA0 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): PA0 Type II PA0 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): PA0 (I): RCOO--CH.dbd.CH.sub.2 PA1 wherein R represents a C.sub.1-4 alkyl group. PA0 (II): CH.sub.2 .dbd.CHCOO--R.sub.1 --O--R.sub.2 PA1 wherein R.sub.1 represents a C.sub.1-4 alkylene group; and R.sub.2 represents a C.sub.1-4 alkyl or alkoxyalkyl group. PA0 (II'): CH.sub.2 .dbd.CHCOO--R.sub.6 PA1 wherein R.sub.6 represents a C.sub.3-8 alkyl group. ##STR1#…
