Abstract

Poly (C.sub.2 -C.sub.4 alkylene terephthalate) molding composition containing mica and a multiphase composite polymer. The multiphase polymer has a first elastomeric phase polymerized from a monomer system including C.sub.1 -C.sub.6 alkyl acrylate as well as crosslinking and graftlinking monomers and has a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase. Preferred compositions also include thermally stable reinforcing fibers such as glass fibers.
