摘要:
Styrenic block copolymers are blended with propylene copolymers to provide polymeric compositions with an improved balance between processability and elasticity. The compositions have improved processability by facilitating the ease with which a rubbery material, usually difficult to melt process, can be processed at high line speeds, which in turn improves the formation of the composition into films or other articles, assisted by a desired level of melt elasticity, i.e., a high elastic extension and recovery.
