A 2,4-dimethylglutarimide, styrene, and cyclohexyl methacrylate containing polymer was prepared by the techniques of copolymerization and glutarimidization. Accordingly an interpolymer of styrene, cyclohexyl methacrylate, and methacrylamide was prepared. In a 1.5 liter, glass reactor fitted with inlet tubes, nitrogen pad, and stirrer, styrene 29 g, cyclohexyl methacrylate 225 g, and methacrylamide 122 g, were introduced, along with 50 percent based o monomer weight of N,N-dimethylformamide solvent. 250 ppm of a peroxide initiator 1,1-bis(t-butylperoxy)cyclohexane was introduced and the reactor heated to 80-100° C. with stirring. Reaction was continued only a short time period (10-20 percent conversion) to prevent polymer compositional drift and possible degeneration of optical properties. The polymer was recovered by precipitation in methanol.
