ABSTRACT:
Saturated, liquid, low molecular weight and low-viscosity isobutylene polymers terminally functionalized by special groups, which correspond to the following formula ##STR1## are produced by solution ozonolysis of high molecular weight isobutylene/diene copolymers containing diene monomers, stabilization of the products obtained after the ozone treatment by addition of peroxide decomposers and subsequent reduction with hydrogen in the presence of hydrogenation catalysts under pressures of 10 to 300 bar and at temperatures of 20.degree. to 300.degree. C., optionally in the presence of sulfur or amines or ammonia.
