Reaction Steps

An acrylic copolymer resin was prepared by feeding 150 parts of toluene into a 500-ml 4-necked flask equipped with a cooling tube, stirrer, and thermometer, heating it to 110° C., adding styrene 40 parts, n-butyl methacrylate 40 parts, ethyl methacrylate 120 parts, methacylic acid 12 parts, benzoyl peroxide 4 parts, and toluene 60 parts spending 3 hours under an inert gas atmosphere, and further heating for 6 hours. This copolymer (designated as acrylic resin-A) was found to have nonvolatile matter content 49.5%, Tg 52° C., polymer acid value 15, and number average molecular weight 28,000.
