Abstract
Abstract Substantially gel free, high molecular weight, high unsaturation copolymers of isobutylene and cyclo-conjugated dienes having a number-average molecular weight of about 30,000 to about 90,000 and a mole % of unsaturation of about 5 to about 45 are prepared by a polymerization in a homogeneous phase, wherein the catalyst which is a hydrocarbyl aluminum dihalide or aluminum halide type catalyst dissolved in an aliphatic type solvent is added to a mixture of the isobutylene, cyclo-conjugated diene, and an aliphatic cosolvent and the polymerization reaction is carried out at a temperature of about -80 DEG to about -110 DEG C.
