1-BUTENE POLYMER AND ITS USE

摘要

Poly-1-butene resin having a limiting viscosity of 1.5-4.0 dl/g, a mol. wt. distribution (ratio of the wt. average mol. wt./the number average mol. wt., Mw/Mn) beinq below 6, and an isotactic value of above 95%. Poly-1-butene resins include 1-butene homopolymer and copolymers contg. small amts. of alpha-olefins. Opt. conventional compounding agents for polyolefin, e.g. weatherproof agents, thermostabilisers, nucleus agents, pigments, dyes may be added to the resins.
