Process for preparing a nonaqueous dispersion of thermosetting film-forming copolymer
Abstract
Abstract AN ACTIVE ETHENIC MONOMER HAVING A FUNCTIONAL EPOXY, HYDROXY OR AMIDE GROUP IS COPOLYMERIZED WITH ANOTHER ACTIVE ETHENIC MONOMER IN THE PRESENCE OF AN ALKYLATED METHYLOLATED COPOLYMER OF ACRYLAMIDE OR METHACRYLAMIDE AND ANOTHER ETHENIC MONOMER DISSOLVED IN A NONAQUOUS MEDIUM. THE NONAQUEOUS MEDIUM IS A MISCIBLE MIXTURE OF AN AROMATIC OR ALCOHOLIC SOLVENT FOR THE METHYLOLATED COPOLYMER AND AN ALIPHATIC NONSOLVENT FOR THE OTHER COPOLYMER. THE REACTION PRODUCES A STABLE DISPERSION OF A POLYMERIC MATERIAL THAT IS INSOULBE IN THE NONAQUEOUS MEDIUM. CURING COATINGS OF THE DISPERSIONS PRODUCES THERMOSETTING FILM HAVING AN EXCELLENT COMBINATION OF PROTECTIVE AND DECORATIVE PROPERTIES.
