ABSTRACT:
An unsaturated copolymer based on olefin which is superior in dynamic fatigue resistance (flexural fatigue resistance), weatherability, fastness to ozone, stability in thermal aging and exhibits also superior performances in chemical reactivity, in processibility and in compatibility as well as co-vulcanizability with aromatic ring-containing resins, such as styrene-butadiene rubber (SBR) etc., and is useful for materials of various rubber products and as modifier for resin products is proposed, said copolymer comprising a structural unit derived from an .alpha.-olefin having 2-20 carbon atoms in a proportion of 30-99.8 mole %, a structural unit derived from an aromatic ring-containing vinyl monomer in a proportion of 0.1-60 mole % and a structural unit derived from a chain-formed non-conjugated triene or tetraene having in the molecule one vinyl group in a proportion of 0.1-10 mole % and said copolymer having an intrinsic viscosity determined in Decalin.RTM. at 135.degree. C. of 0.05-10 dl/g.
