Zusammenfassung:1291185 Cyclopentene polymerization in two stages FARBENFABRIKEN BAYER AG 23 March 1970 [27 March 1969] 13880/70 Heading C3P Cyclopentene is polymerized in the presence of an organoaluminium compound, a compound of Group IVa or Va, and optionally a compound containing -O-H, -O-O-, a halogen or an epoxide group, in two stages with the addition of an acyclic or polycyclic diolefinic hydrocarbon or an acyclic or bicyclic monoolefinic hydrocarbon. A rubber extending oil may be added during or after the second stage. In examples cyclopentene is polymerized in the presence of WCI 6 -epichlorohydrin, Et 2 AlCl and isoprene, butene-1, hexadiene-1,4, norbornadiene or dicyclopentadiene added in the second stage, TaCl 5 -vinylidene chloride-EtAlCl 2 -butadiene or norbornadiene in the second stage and optionally butene-1 in the first stage, WCl 6 -2-chloroethanol-Et 2 AlCl-isoprene in the second stage and butene-1 in the first stage.
