The process of radical binary copolymerization of butyl methacrylate and α-methyl styrene in a solvent has been carried out and optically transparent copolymers at various molar ratios have been synthesized. The copolymers synthesized based on butyl methacrylate and α-methyl styrene have relatively high refraction coefficient ( =1.5880) and transmission values (about 86%). The copolymerization constants values (r₁ and r₂) of the above-mentioned monomer pairs have been found and Q-e parameters have been calculated. The microstructure of the obtained copolymer samples of the butyl methacrylate with α-methyl styrene has been determined
