Process for preparing alkyd-acrylic graft copolymers
Abstract
Abstract THE NOVEL PROCESS OF THIS INVENTION IS DIRECTED TO THE PREPARATION OF GRAFT COPOLYMERS HAVING AN ALKYD RESIN BACKBONE AND SIDE CHAINS OF POLYMERIZED ETHYLENICALLY UNSATURATED MONOMERS AND COMPRISES THE FOLLOWING STEPS: (1) BLENDING AN ALKYD RESIN HAVING REACTIVE HYDROXY GROUPS WITH SIDE CHAIN MONOMERS OF A HYDROXY-CONTAINING ACRYLIC MONOMER AND OTHER ETHYLENICALLY UNSATURATED MONOMERS SUCH AS STYRENE, ALKYL METHACRYLATE, ALKYL ACRYLATE, ACRYLONITRILE, METHACRYLONITRILE OR MIXTURES OF THESE MONOMERS AND A POLYMERIZATION CATALYST; (2) REACTING THE MIXTURE OF ABOUT 2-15 HOURS AND (3) ADDING A MELAMINE RESIN OR A UREA/FORMALDEHYDE RESIN AND AN ACID CATALYST TO THE REACTION MIXTURE AND CONTINUING THE POLYMERIZATION REACTION TO FORM THE GRAFT COPOLYMER.
