Abstract: | Summary
Radiation-induced graft polymerization of N,N-dimethylaminoethylmethacrylate (DMAEMA) from solutions in carbon tetrachloride
or in chloroform onto bisphenol A-derived polycarbonate (PC-1) and allyl diglycol carbonate (PC-2), respectively, was carried
out by method of preirradiation in air. It has been found essential difference in transparency and durability of the modified
PC-1 and PC-2. Effects of preirradiation dose as well as temperature and time of graft polymerization on effectiveness of
DMAEMA grafting onto PC-2 were investigated, the optimal values of dose and temperature are 500 kGy and 55°C, respectively.
