摘要
采用红外光谱（ＩＲ）、核磁共振（１Ｈ－ＮＭＲ）、气相色谱－质谱（ＧＣ／ＭＳ）和气相渗透（ＶＰＯ）等方法对环氧乙烷－四氢呋喃共聚合中产生的环状齐聚物（ＯＣＥ）的结构和组成进行了分析鉴定。结果表明，ＯＣＥ是环氧乙烷和四氢呋喃的结构单元按不同比例组成的混合物，其分子量较低，约为３００～５００。
In this paper, the structure and composition of the oligomeric cyclic ether(OCE) formed during the copolymerization of ethylene oxide with tetrahydrofuran were identified by IR, 1HNMR, GC/MS and VPO methods. The results show that the OCE is a compound which is composed of different ratio of EO units to THF units. It has lower numberaverage molecular weight, about 300￣500.
