Abstract

Abstract Translated from Japanese (57)【要約】 【解決手段】 本発明の鎖状ポリエン基含有ノルボルネ ン化合物は、一般式[I]: 【化1】 [式[I]中、nは1〜5の整数であり、R 1 は炭素数1 〜5のアルキル基であり、R 2 およびR 3 はそれぞれ独立 して水素原子または炭素数1〜5のアルキル基であ る。]で表わされる。本発明の不飽和性エチレン系共重 合体は、エチレン単位(i)30〜92モル%と特定のα- オレフィン単位(ii)6〜70モル%と、上記ノルボルネ ン化合物[I]単位(iii)0.1〜30モル%とのランダ ム共重合体であり、モル比[(i)/(ii)]が40/60 〜92/8であり、単位(iii)が特定の式で表され、極 限粘度[η]が0.05〜10dl/gである。 【効果】 この新規な不飽和性エチレン系共重合体は、 耐候性、耐熱性および耐オゾン性に優れており、かつ加 硫速度が速い。 (57) Abstract: A chain polyene group-containing norbornene compound of the present invention has the general formula [I]: [In the formula [I], n is an integer of 1 to 5, and R 1 has 1 carbon atom. And R 2 and R 3 are each independently a hydrogen atom or an alkyl group having 1 to 5 carbon atoms. ]] Is represented. The unsaturated ethylene-based copolymer of the present invention has an ethylene unit (i) of 30 to 92 mol% and a specific α- A random copolymer of an olefin unit (ii) of 6 to 70 mol% and the norbornene compound [I] unit (iii) of 0.1 to 30 mol% and a molar ratio [(i) / (ii)]. 40/60 ˜92 / 8, the unit (iii) is represented by a specific formula, and the intrinsic viscosity [η] is 0.05 to 10 dl / g. [Effect] This novel unsaturated ethylene-based copolymer is It has excellent weather resistance, heat resistance and ozone resistance, and has a fast vulcanization rate.
