摘要： 合成了一种新的三元引发剂[C2H5C(CH2OCH2CH2CO+ClO4-)3],并用于制备聚四氢呋喃三元醇.用1HNMR,FTIR和GPC法对聚合物的结构进行了表征.结果表明,产物中环状齐聚物的含量极低.对聚合物水解产物的分子量及分子量分布测定结果表明,产物为预期的三元醇,聚合反应过程中链转移可以忽略,聚合物的分子量可控.

Abstract: New oxacarbenium perchlorate, C2H5C(CH2OCH2CH2CO+ClO4-)3, was synthesized and used in the preparation of poly(tetrahydrofuran) (PTHF) triol. The product structure was determined by 1H NMR and FTIR. GPC curves show that the cyclic oligomers were negligible. Molecular weight and distribution of branch chain were obtained by analyzing the hydrolyzed products of PTHFs. All the results demonstrate that PTHF triol was obtained, both inter- and intra-molecular chain transfer reactions were negligible and molecular weight could be controlled.

Key words: Poly(tetrahydrofuran) triol, Cationic ring-opening polymerization, Multifunctional initiator
