ABSTRACT:
Novel, well-defined thermoplastic block copolymers containing polyarylate and polyamide blocks. Preferably formed via a cycloaddition reaction of a polyamide having at least one terminal double bond, with a polyarylate having at least one dihydroarylcyclobutenyl moiety. They display excellent mechanical properties, improved UV, solvent and stress-crack resistance; good heat resistance and are easy to melt fabricate. They show good compatability with the corresponding homopolymers and are uniquely suited as compatibilizing agents for polyamide-polyarylate blends.
