| 摘 要： | 阳离子开环聚合制备端羟基聚环氧氯丙烷(PECH)时,往往伴随着一定量齐聚物的生成而使聚醚质量劣化。溶剂萃取法可有效去除相对分子质量为700￣5300的PECH的齐聚物。实验表明,处理不同相对分子质量的PECH,应采用不同的萃取溶剂。

| Abstract: | Oligomers are often formed in the preparation of hydroxy-terminated polyepichlorohydrin(PECH) by cation ring- opening polymerization, so that quality of PECH is reduced. Solvent extraction method can effectively remove the oligomer with relative molecular mass of 700￣5300 from PECH. It is discovered through experiment that treating PECHs with different relative molecular mass should use different extraction solvents. |
