Abstract

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

Highlights

One of the most modern directions of the development of optically transparent polymers is the synthesis of binary or ternary copolymers with a complex of unique properties
It has been carried out the turbidimetric titration for clarification whether homopolymers of monomers are formed during their copolymerization reaction
The fractional and chemical and IR spectral analyses of these fractions have been carried out and it has been found that the results practically are not differed. This fact indicates that butyl methacrylate (BMA) and α-MC homopolymers are not formed in the investigated binary system
