Influence of addition of polyethylene-block-polyacrylate copolymer on the impact strength of PP/EPDM/talc composites

摘要

Polypropylene(PP)-elastomer blend owes its excellent impact strength to blending with an elastomer of lower modulus than the matrix,but since the modulus decreases as more of the elastomer is added,PP-elastomer blend is used as a talc-filled composite,which affords a high modulus enhancement effect.
