Procedure

To a monomer mixture including 93.2 parts by mass of methyl methacrylate, 2.3 parts by mass of methyl acrylate and 3.3 parts by mass of xylene, 0.03 part by mass of 1,1-di-t-butylperoxy-3,3,5-trimethyl cyclohexane and 0.12 part by mass of n-octylmercaptan were added and uniformly mixed therein. The solution was continuously supplied to a sealed type pressure resistant reactor having an inner volume of 10 L. Polymerization reaction was carried out at an average temperature of 130° C. for an average retention time of two hours while stirring, and then the reaction solution was continuously sent to a storage tank connected to the reactor to remove volatile portions therefrom under constant conditions. The melted solution was further continuously transferred to an extruder to obtain pellets of a methyl methacrylate-methyl acrylate copolymer (b-2).
