摘要： A rubber composition useful as a tire side wall or tire tread is formed from an unsaturated olefin copolymer (A) or (A′) and diene rubber (B). Copolymers (A) and (A′) are each obtained from (i) ethylene, (ii) aromatic vinyl compound, (iii) non-conjugated polyene, and, optionally (iv) alpha-olefin having at least 3 carbon atoms. When used in forming a tire side wall, copolymer (A) has a molar ratio of (i)/(iv) from 100/0 to 40/60; molar ratio of [((i)+(iv))/(ii)] from 98/2 to 60/40; an intrinsic viscosity, measured in decalin, at 135° C., from 1.0 to 6.0 dl/g; and iodine value from 10 to 50. For use in tire tread, copolymer (A′), has a molar ratio (i)/(iv) from 100/0 to 40/60; molar ratio [((i)+(iv)):(ii)] from 99/1 to 85/15. The weight ratio (A′)/(B) is from 1/99 to 50/50. The compositions for tire side wall are characterized by excellent strength properties and bending fatigue resistance and low fuel consumption. The compositions for tire tread are characterized by superior strength properties, abrasion resistance and braking performance on wet road (wet ski resistance) and small rolling resistance.

摘要： The higher .alpha.-olefin copolymer of the invention is a copolymer of specific higher .alpha.-olefin, specific .alpha.,.omega.-diene and specific non-conjugated diene, and this copolymer has a specific molar ratio of the higher .alpha.-olefin to the .alpha.,.omega.-diene, a specific content of the non-conjugated diene and a specific intrinsic viscosity. This higher .alpha.-olefin copolymer can be prepared using a catalyst for olefin polymerization formed from a specific solid titanium catalyst component, an organometallic compound catalyst component and an electron donor catalyst component. The vibration-insulating rubber molded product of the invention is formed from a vulcanized product of the above-mentioned copolymer. The above-mentioned copolymer is excellent not only in weathering resistance, ozone resistance, thermal aging resistance, low-temperature characteristics, vibration-damping properties and dynamic fatigue resistance but also in processability, so that an excellent vulcanized product can be obtained from the copolymer.

摘要： 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.
