Graft polymer of a vinyl monomer and a polyester,and a butadiene polymer
Abstract
Abstract GRAFT COPOLYMERS ARE PRODUCED BY REACTING A POLYMERIZABLE MONOMER WITH A POLYESTER OF A POLYCARBOXYLIC COMPOUND AND A POLYHYDRIC ALCOHOL, WHEREIN THE POLYESTER COMPRISES A MAXIMUM OF 5 MOLE PERCENT OF CARBOXYLIC AND HYDRIC COMPONENTS WHICH CONTAINS ALIPHATIC CARBONTO-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 PRODUCTS. THE POLYMER PRODUCTS ARE SUITABLE FOR PRODUCING MOLDED ARTICLES, LAMINATES, EXTRUDED PRODUCTS, PROTECTIVE COATINGS, AND THE LIKE, WHICH HAVE SUPERIOR TOUGHNESS, HIGH-IMPACT STRENGTH, FIRE RESISTANCE AND CHEMICAL RESISTANCE.
