HIGHLY REACTIVE POLYISOBUTYLENE HAVING A HIGH PERCENTAGE OF VINYLIDENE DOUBLE BONDS IN THE SIDE CHAINS

摘要

Polyisobutylene having a total percentage of vinylidene double bonds of more than 50 mol.% and a number average molecular weight of 500 to 10,000 daltons, wherein at least 10% of all the vinylidene double bonds in the polyisobutylene are in one or more side chains composed of at least 2 carbon atoms on the polyisobutylene main chain. Polyisobutylene of this type is suitable for producing fuel additives and lubricant additives.
