Toughened polymeric polyblend having high flow and ductility

摘要

The present invention relates to a toughened polymeric polyblend having high flow and ductility comprising a polymer of polyvinylidene aromatic monomer having dispersed therein a diene rubber grafted with said monomer and a block copolymer of said monomer and a diene monomer, said block copolymer comprising about 55 to 90 weight percent of a monovinylidene aromatic monomer and about 10-45 weight percent of a diene monomer.
