摘要 |
A powder coating is prepared by (a) solvent polymerizing carboxy-functional acrylate copolymers, (b) separating and reacting the copolymers with a molar excess of at least one epihaloalkane, (c) removing excess epihaloalkane, (d) adding toluene and then reacting the copolymers with a sodium hydroxide solution to produce epoxy groups-containing acrylate copolymers having an epoxide number of from 0.018-0.501 eq/100 g copolymer, a weight average molecular weight of from 1000-30,000 and a Tg of from 20-120 DEG C.; and (e) extruding the epoxy groups-containing acrylate copolymers with a hardener such as aliphatic polybasic acids or anhydrides, or carboxy-functional polyesters or acrylic resins along with additives such as pigments or fillers. |
