ABSTRACT:
This disclosure is concerned with flame retarded polyethylene terephthalate compositions which have enhanced drip suppression due to the incorporation of a two-phase polyacrylate comprised of a cross-linked elastomeric first phase to which a rigid thermoplastic second phase has been grafted. These compositions have enhanced crystallization velocities and therefore may be molded into colder molds and with shorter mold cycles than has been conventional for polyethylene terephthalate compositions.
