Graft polymer of a vinyl monomer and a fire retardant polyester
Abstract
Abstract GRAFT CONOLYMERS ARE PRODUCED BY REACTING A POLYMERIZABLE MONOMER WITH A POLYESTER OF A POLYCARBOXYLIC COMPOUND AND A POLYHYDRICX ALCOHOL, WHEREIN THE POLYESTER COMPRISES A MAXIMUM OF 5 MOLE PRECENT OF CARBOXYLIC AND HYDRIC COMPONENTS WHICH CONTAINS ALIPHATIC CARBON-TO CARBON UNSATURATION. HALOGEN-CONTAINING POLYESTERS AND PHOSPHORUS-CONTAINING POLYESTERS ARE PARTICULARLY USEFUL IN PRODUCING FIRE-RETARDANT GRAFT COPOLYMERS. THE GRAFT COPOLYMERS CAN BE BLENDED WITH A POLYMER OF BUTADIENE, SUCH AS A GRAFT COPOLYMER OF A POLYMERIZABLE MONOMER AND POLYBUTADIENE TO PRODUCE ADDITIONAL USEFUL PRODUCTS. THE POLYMER PRODUCTS ARE SUITABLE FOR PRODUCING MOLDED ARTICLES, LAMINATES, EXTRUDED PRODUCTS, PROTECTIVE COATING, AND THE LIKE, WHICH HAVE SUPERIOR TOUGHNESS, HIGH-IMPACT STRENGTH, FIRE RESISTANCE AND CHEMICAL RESISTANCE.
