摘要： 本文用液相色谱和凝胶色谱对双酚A、双酚S型低聚芳砜及α,ω-双甲基丙烯酸聚芳砜酯大分子单体进行了组分分析,通过改合成条件、测定数均分子量等辅助手段确定液相色谱各峰的归属,计算其分子量及分子量分布指数,并对两种方法测定的结果进行了比较。用液相色谱观察低聚体每个组分的含量及其反应过程中的消长情况比凝胶色谱清晰。

Abstract: Bisphenol A-type and bisphenol S-type poly(ether-sulfone)s oligomer and a,w-bis(methacrylate)poly (ether-sulfone)s macromer was analysized by high-performance liquid chromatography (HPLC) and gel permeation chroma-tography(GPC). Some excellent separations of oligomeric mixture and macro-meric mixture were obtained. All peaks of HPLCwere identified. Number-average molecular weight(Mn), weight-average molecular weight (M w) obtained from HPLC were compared with those obtained from VPO and GPC. The polymerization processes of poly(ether-sulfone)s in DMSO and sulfolane was compared by HPLC and GPC.

Key words: Poly(ether-sulfone)s oligomer, Bivinyl macromer, Analyzed by GPC and HPLC
