THERMOPLASTIC GRAFT COPOLYMERS AND THEIR USE AS COMPATIBLIZERS

摘要

Graft copolymers are disclosed having formula (I), wherein R and R' are hydrogen, alkyl, and the primary and secondary alkyl halides, a ranges from about 14 to 70,000, b ranges from 0 to about 70,000, c ranges from 0 to about 70,000, d ranges from about 1 to 70,000, X comprises a halogen, and Nu is a nucleophilic residue provided by a thermoplastic polymeric nucleophile having a molecular weight of at least about 1,000 and being sufficiently nucleophilic such that said nucleophile is capable of donating electrons to benzyl halides. Methods for compatibilizing polymer blends utilizing such graft copolymers are also disclosed.
