Abstract
A copolymer of chloroprene(CP) and glycidylmethacrylate(GMA) (poly(CP-Go-GMA))was prepared by radical solution copolymerization in benzene. The copolymer was characterixed by FT-IR and 1H-NMR spectrophotomrters, and differential scanning calorimetry(DSC).DSC analysis showed that the copolymer was amorphous and had glass transition temperature of about -16.4℃. The monomer reactivity ratios were given as r1(CP) = 3.85 and r2(GMA)=0.19 in the copolymerization of CP and GMA. Thermal suability and the light resistance of the copolymer wereb measured using a thermogravimetric analyzer(TGA) and Fade-o-meter, respectively. It was found that the copolymer showed slightly lower thermal stability than that of polychloroprene(CR), while the copolymer showed fairly better light resistance under the environmental conditions both exposed to U. V. light and heat.
