摘要

1493248 Copolymers of cyclopentene and dicyclopentadiene B F GOODRICH CO 1 Nov 1974 [5 Nov 1973] 30021/77 Divided out of 1493247 Heading C3P Copolymers of cyclopentene and dicyclopentadiene comprise 35 to 98% by weight of dicyclopentadiene and 0À01 to 0À3 mole per mole of cyclopentene plus dicyclopentadiene of at least one acyclic monoolefin or a non-conjugated acyclic polyolefin containing up to 12 carbon atoms and having at least one hydrogen on each double bonded carbon atom. The exemplified copolymers are prepared using butene-1 as the monoolefin and a catalyst comprising WCl 6 and AlEt 2 I and combined with t-butyl p-cresol.
