Abstract

Statistical AB-block copolymers having improved properties, a process for their manufacture and their use. Tire treads made of the statistical AB block copolymers according to the invention are characterized by high skid resistance under wet conditions combined with persistently low abrasion, good dynamic properties and rapid vulcanization.
