IMPACT IMPROVEMENT OF PBT WITH TWO IMPACT MODIFIER

摘要

The present invention contains (1) acrylonitrile and butadiene unit-containing polymers in an amount of impact improving, and (2) (a) ethylene, (b) lower alkyl acrylate and one oxygen atom as a hetero atom. A polybutylene terephthalate composition is provided that contains an impact modifier that is a synergistic mixture of a monomer containing a heterocycle with a terpolymer.
