Abstract 1. A MOLDING MIXTURE WHICH COMPRISES A PARTICULATE INTIMATE MIXTURE OF: (A) AN EPOXY-FUNCTIONAL COPOLYMER OF ACRYLIC MONOMERS (1) CONSISTING ESSENTIALLY OF ABOUT 15 TO ABOUT 40 WEIGHT PERCENT GLYCIDYL METHACRYLATE, ABOUT 10 TO ABOUT 30 WEIGHT PERCENT METHACRYLONITRILE, AND A REMAINDER CONSISTING ESSENTIALLY OF METHYL METHACRYLATE, AND (2) HAVING AN AVERAGE MOLECULAR WEIGHT IN THE RANGE OF ABOUT 1,500 TO ABOUT 16,000, WITH LESS THAN 5 PERCENT OF THE MOLECULES OF SAID COPOLYMER HAVING A MOLECULAR WEIGHT BELOW 1,000, A SOFTENING POINT ABOVE 25*C., AND EPOXIDE GROUPS IN ITS MOLECULAR STRUCTURE RESULTANT OF INCLUSION OF SAID GLYCIDYL METHACRYLATE AS A CONSTITUENT MONOMER THEREOF, AND (B) A C4-C20 DIBASIC ACID HAVING MELTING POINT IN THE RANGE OF 30* TO 160* C., SAID DIBASIC ACID BEING REPRESENT IN AN AMOUNT WHICH PROVIDES ABOUT 0.8 TO ABOUR 1.2 CARBOXYL GROUPS PER EACH EPOXY GROUP IN THE MOLDING POWDER.
A MOLDING MIXTURE WHICH COMPRISES A PARTICULATE INTIMATE MIXTURE OF: (A) AN EPOXY-FUNCTIONAL COPOLYMER OF ACRYLIC MONOMERS (1) CONSISTING ESSENTIALLY OF ABOUT 15 TO ABOUT 40 WEIGHT PERCENT GLYCIDYL METHACRYLATE, ABOUT 10 TO ABOUT 30 WEIGHT PERCENT METHACRYLONITRILE, AND A REMAINDER CONSISTING ESSENTIALLY OF METHYL METHACRYLATE, AND (2) HAVING AN AVERAGE MOLECULAR WEIGHT IN THE RANGE OF ABOUT 1,500 TO ABOUT 16,000, WITH LESS THAN 5 PERCENT OF THE MOLECULES OF SAID COPOLYMER HAVING A MOLECULAR WEIGHT BELOW 1,000, A SOFTENING POINT ABOVE 25*C., AND EPOXIDE GROUPS IN ITS MOLECULAR STRUCTURE RESULTANT OF INCLUSION OF SAID GLYCIDYL METHACRYLATE AS A CONSTITUENT MONOMER THEREOF, AND (B) A C4-C20 DIBASIC ACID HAVING MELTING POINT IN THE RANGE OF 30* TO 160* C., SAID DIBASIC ACID BEING REPRESENT IN AN AMOUNT WHICH PROVIDES ABOUT 0.8 TO ABOUR 1.2 CARBOXYL GROUPS PER EACH EPOXY GROUP IN THE MOLDING POWDER.
