ABSTRACT:
Novel blends have been discovered comprising: (A) a polyamide; (B) a polymer that is miscible with polystrene; and (C) a compatibilizer comprising a copolymer having repeating units derived from an aromatic vinyl compound monomer and repeating units derived from vinylphenol monomers, wherein at least about 50% of said aromatic vinyl compound monomers are styrene monomeric units. The blends show improvements in mechanical properties as compared to similar blends without the compatibilizer.
