Abstract
zs An amino group-containing copolymer which is composed of (A) butadiene, isoprene or both of them, (B) acrylonitrile and (C) a (meth)acrylate represented by the general formula (I): ##STR1## wherein R is H or CH.sub.3, R.sub.1 and R.sub.2 are independently alkyl groups having 2 to 8 carbon atoms, and X is an alkylene group having 2 to 4 carbon atoms, and has a polymer composition (weight %) of (A):(B):(C) of 30 to 89.9:10 to 50:0.1 to 20. Said multi-component copolymer is used as oil-resistant rubber, and is particularly excellent in resistance to growth of crack by solvent.
