Abstract
Isobutene polymers having a mean degree of polymerization P of from 10 to 100 and a proportion E of double bonds, capable of reaction with maleic anhydride, of from 60 to 90%, where E=100% corresponds to the calculated theoretical value for the case where each molecule of the isobutene polymer contains such a reactive double bond.
