Reaction Conditions

Reaction Steps

Into a reactor were charged 80 parts of toluene, 20 parts of isobutanol, 6 parts of dimethylaminoethyl methacrylate, 40 parts of methyl methacrylate, 20 parts of styrene, 20 parts of butyl acrylate, 20 parts of butyl methacrylate, 14 parts of n-butyl methacrylate, 1 part of n-dodecylmercaptan and 1 part of azobisisobutyronitrile. They were stirred at 80° C. for 2 hours. Then, 0.2 part of azobisisobutyronitrile was added 5 times at 2-hour intervals, and polymerization was completed in 16 hours. Thus, there was produced an acrylic copolymer resin solution for rigid product grade which had a glass transition temperature (Tg) of 70° C.
