Acrylic modifiers for polycarbonamides

Abstract

Abstract AN IMPACT RESISTANT NITROGENOUS POLYMER COMPRISES A MULTIPHASE AMINE-REACTIVE MOIETY-CONTAINING POLYMER GRAFTED TO A POLYCARBONAMIDE CONTAINING RECURRING AMIDE LINKAGES AS AN INTEGRAL PART OF THE POLYMER CHAIN; THE GRAFTING, BY REACTION OF AN AMINE-REACTIVE MOIETY OF THE POLYMER WITH AN AMINAL GROUP OF THE POLYACARBONAMIDE. PREFERABLY THE AMINE-REACTIVE MOIETY-CONTAINING POLYMER IS A MULTIPHASE CARBOXYLIC ACID-CONTAINING POLYMER COMPRISING (A) A FIRST ELASTOMER PHASE THAT IS PREFERABLY POLYMERIZED FROM MONOMERS COMPRISING; 50 TO 99.9 PARTS BY WEIGHT ALKYL ACRYLATE WHEREIN THE ALKYL GROUP CONTAINS 1 TO 15 CARBON ATOMS, BUTADIENE OR SUBSTITUTED BUTADIENE; 0 TO 40 PARTS BY WEIGHT OF OTHER ETHYLENICALLY UNSATURATED MONOMERS; 0 TO 5 PARTS BY WEIGHT OF A POLYETHYLENICALLY UNSATURATE CROSSLKING MONOMER; AND 0 TO 5 PARTS BY WEIGHT OF A GRAFT-LINKING MONOMER; AND (B) A FINAL RIGID THERMOPLASTIC STAGE CONTAINING AMINE-REACTIVE CARBOXYLIC ACID GROUPS AND POLYMERIZED FROM MONOMERS COMPRISING; 0.1 TO 50 PARTS BY WEIGHT OF A COPOLYMERIZABLE CARBOXYLIC ACID; 50 TO 99.9 PARTS BY WEIGHT OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALKYL METHACRYLATES. STYRENES. ACRYLONITRILE, METHACRYLONITRILE AND OLEFINS THAT, WHEN HOMOPOLYMERIZED, FORM POLYMERS HAVING A HEAT DISTORTION TEMPERATURE GREATER THNA BOUT 20* C.; 0 TO 49 PARTS BY WEIGHT OF ANOTHER ACRYLIC MONOMER; AND 0 TO 40 PARTS OF ANOTHER ACRYLIC MONOMER; UNSATURATED MONOMER. THE IMPACT RESISTANT NITROGENOUS POLYMER IS CHARACTERIZED BY SUPERIOR HOT STRENGTH THAT RENDERS THE POLYMER EXTRUDABLE, BLOW MOLDABLE, AND INJECTION MOLDABLE.
