Abstract
The present invention relates to block copolymers which are predominantly based on vinylcyclohexane and to a process for producing them. The block copolymers can be processed to form mouldings by extrusion or injection moulding. The mouldings which result therefrom are distinguished by their high resistance to thermal deformation, good mechanical properties, high transparency in the visible and near UV range, and by their particularly low birefringence and water absorption.
