摘要： 在“拟高稀释”条件下,通过亲核缩聚反应高产率地合成了含硫醚键的芳香醚环状低聚物.应用核磁、GPC和激光质谱(MALDI-TOFMS)等手段对环状低聚物的结构进行了确认,并研究了环状低聚物的组分分布.聚硫醚醚酮环状低聚物在硫醚自由基的引发下进行快速熔融聚合,得到热稳定性很好的高分子量线性聚合物.

关键词: 聚硫醚环状低聚物, 硫醚自由基, 自由基开环聚合

Abstract: Two kinds of novel macrocyclic aryl thioether ether oligomers were synthesized by nucleophilic condensation reaction in high yields under pseudo high dilution condition. Acombination of 1H NMR, GPCand MALDI-TOF MSanalyses unambiguously confirmed the cyclic nature and their distributions. Macrocyclic thioether ether ketone oligomers can undergo facile melt ring opening polymerization(ROP) initiated by thiyl radical to give a high molecular weight polymer.

Key words: Macrocyclic thioether ether oligoemrs, Thiyl radical, Free-radical ring opening polymerization
