Synthesis and Characterization of 2-Methacryloyloxyisopro-panol Ester of Dehydroabietic Acid
摘要
Abstract
2-Methacryloyloxyisopropanol ester of dehydroabietic acid(DAGMA)was synthesized by esterification of dehydroabietic acid and glycidyl methacrylate.The effects of reaction time,reaction temperature,amount and type of catalyst on the yield of dehydroabietic acid derived monomer were investigated.The resulting product was then characterized by FT-IR,1H NMR,13C NMR,DSC and GPC respectively.The results showed that the optimal conditions for the reaction were as follows: triethylamine as catalyst at an amount of 2％of dehydroabietic acid,reaction time 5 h,reaction temperature 120 ℃,and the esterification rate was about 85％.DSC test showed that in the presence of initiator AIBN,the suitable conditions for synthesis of DAGMA was n(DA):n(GMA)1:1.It showed that DAGMA could be polymerized in the presence of initiator.The weight average molecular weight(Mw)of the asprepared homopolymer was 23 900,the number average molecular weight(Mn)was 12 254,and its glass transition temperature was around 62.61 ℃.关键词
