Summary

Homopolymers and copolymers of various composition of methyl, ethyl, n-butyl and cyclohexyl methacrylates were prepared by bulk copolymerization method. These products were investigated by IR spectrometry and *HNMR analysis. For copolymers of selected compositions the refractive indices ≫D/ ≫d°/ ”f° and He5 were determined by the microscope method using specimens in the form of film and sheet. From these values the average dispersions and Abbe numbers were calculated. Some properties of these homo- and copolymers were also determined (a.o. Brinell hardness, Vicat temperature).
