摘要
以1,4-丁二醇(BDO)为起始剂、三氟化硼乙醚(BF_3·Et_2O)为催化剂、二氯甲烷(CH_2Cl_2)为溶剂、由3-溴甲基-3-(2-氰乙氧基)甲基氧丁环(BMCMO)开环聚合,首次合成出溴化聚醚PBMCMO,并借助红外光谱完成了结构鉴定。利用GPC、TGA、羟值分析等测试方法完成了聚合物的性能表征。
At the present of catalyst BF3·Et2O , using 1,4-butanediol as iniriator and CH2Cl2 as solvent ,the ho-mopolymer(PBMCMO) was prepared by the ring-opening polymerization of monomer 3-bromomethyl-3-(2-cynoethyl) methyl oxetane (BMCMO). The structures of products were identified by IR, and the propertis were characterized by GPC, TGA and determination of hydroxyl equivalent.
