本文系统地研究了1,5-环辛二烯(COD)在 BF_3·OEt_2和 AlCl_3催化下的阳离子型跨环聚合.考察了引发剂、助催化剂以及溶剂等因素对单体转化率的影响.得到的齐聚物数均分子量为1000左右,软化温度为140—160℃.采用裂解色谱-质谱证明产物具有1的结构.
In this paper, the cationic cross-ring polymerization of 1,5-cyclooctadiene (COD) catalyzed by BF_3 · OEt_2 and AlCl_3 was systematically investigated. The effects of initiator, cocatalyst and solvent on the monomer conversion were investigated. The resulting oligomer has a number average molecular weight of about 1000 and a softening temperature of 140-160 ° C. The structure of the product was confirmed to be 1 by pyrolysis chromatography-mass spectrometry.
