This article demonstrates how copolymerization can be used to improve the quality of polyalkyl methacrylates. Benzoyl peroxide was used as an initiator for copolymerization performed in toluene solution. The influences of the concentrations of initiator and monomer mixture in toluene, the temperature, the length of the reaction period, and the quantity of styrene were investigated. The results indicate that as the reaction temperature was raised from 70/sup 0/ to 90/sup 0/C, the molecular weight of the copolymer decreased from 20,000 to 12,000 and the yield remained unchanged. An increase in the content of styrene from 10% to 40% led to an increase in the molecular weight of the copolymer from 10,000 to 17,000. When the volume ratio of toluene to monomer mixture was increased, the molecular weight of the copolymer decreased while the yield remained constant. It is determined that by varying the quantities of stryene and toluene, the molecular weight of the copolymer can be regulated without changing the temperature or the initiator concentration.
