摘要
以偶氮二异丁腈(AIBN)为引发剂,研究了α-蒎烯与苯乙烯的自由基本体共聚反应。从~1H NMR谱、IR光谱、元素分析、热重分析、溶解度和特性粘数等方面对共聚物进行了表征,初步探讨了共聚反应机理,探讨了共聚单体投料比、聚合时间、聚合反应温度和引发剂用量等因素对共聚反应的影响。α-蒎烯与苯乙烯共聚产物,可望成为萜烯树脂系列的新品种。
Free-radical bulk copolymerization of α-pinene and styrene was performed using AIBN as initiator. It was found that styrene formed copolymer with α-pinene at all monomer ratios. The mechanism of copolymerization of a-pinene and styrene was suggested. The copolymer was characterized by 1H NMR, IR, solubility, intrinsic viscosity,and elemental and TG analysis. The effects of monomer composition, reaction time, temperature and amount of AIBN on the copolymerization of α-pinene with styrene were examined. The copolymer was a white powder or elastic solid with commercial value.
