摘要

Abstract

Bomylene-sulfurdioxide polysulfone resin( BE-SO2 )was synthesized by free radical copolymerization of monomers SO2 and bomylene (BE) which synthesized from α-pinene. Similarly, BE-SO2-Ma and BE-SO2-St were synthesized using BE,SO2, maleie anhydride (MA) as monomers and BE, SO2, styrene (St) as monomers respectively. Effects of operating conditions such as monomer ratio, polymerization temperature and reaction time on the copolymer yields are discussed. The results showed that the optimum reaction conditions are as follows∶ reaction temperature -20 ℃, reaction time 4 h, n(BE) 1 mmol, n(BE)∶n(Ma) 1∶ 1, n(BE)∶ n(St) 1∶ 1, CYC as solvent and volume 4 mL, and the highest yield of BE-SO2, BE-SO2-Ma, BE-SO2-St are 70 % ,64 % and 71%, respectively. The structure of the copolymers were characterized by FT-IR, GPC, DSC, EA and SEM. BE-SO2 was a black solid powder with weight average molecular weight( Mw) of 1 069, number average molecular weight (Mn ) of 376, and Tg of 134.5 ℃; BE-SO2-Ma polysulfone resin is a dark brown solid powder with Mw of 1 576, Mn of 402and Tg of 152.0 ℃; BE-SO2-St polysuffone resin is a tan solid powder with Mw of 33 054, Mn of 952 and Tg of 174.8 ℃.
