Abstract
A novel process is used to prepare synthetic rubbers (B) which feature very narrow molecular weight distribution and a correspondingly low value for the polydispersity index. The preparation process encompasses the treatment of a synthetic rubber with ultrasound, where the resultant synthetic rubber (B) has a lower weight-average molecular weight (M) than the synthetic rubber (A) used. The resultant synthetic rubbers (B) have excellent suitability for processing via extruder processes or injection-molding processes.
