ABSTRACT:
There have been provided by the present invention a higher .alpha.-olefin copolymer which has an intrinsic viscosity [.eta.], as measured in decalin at 135.degree. C., of 0.1 to 10 dl/g, and comprises polymer units derived from 95-30 parts by mol of a higher .alpha.-olefin of C.sub.6-20, 5-70 parts by mol of an aromatic ring-containing vinyl monomer represented by the formula [I] (total of the higher .alpha.-olefin and the vinyl monomer are 100 parts by mol), and 0.01 to 30% by mol of a non-conjugated diene represented by the formula [II]; ##STR1## wherein n is an integer of 0 to 5, and R.sup.1, R.sup.2 and R.sup.3 are each independently H or C.sub.1-8 alkyl; ##STR2## wherein n is an integer of 1 to 5, R.sup.4 is C.sub.1-4 alkyl, R.sup.5 and are each independently H or C.sub.1-8 alkyl but are not H simultaneously, a process for the preparation thereof, a higher .alpha.-olefin copolymer composition comprising [A] the higher .alpha.-olefin copolymer and [B] a diene rubber, and a rubber molded product comprising a vulcanized product of the higher .alpha.-olefin copolymer.
