氢转移聚合反应的研究

Studies on Hydrogen Transfer Polymerization

羟乙基丙烯酸酯(HEA)进行游离基型聚合,生成聚羟乙基丙烯酸酯(PHEA)的研究已有报道,但有关该化合物氢转移聚合反应仅有Saegusa等进行过研究,而在钠催化下的氢转移聚合反应却未见报道。本文研究了HEA在钠作用下的氢转移聚合反应,用IR、NMR、VPO和元素分析等手段研究了它的结构和分子量,讨论了反应机理。

This paper reports sodium-catalyzed hydrogen transfer polymerization of hydroxyethyl aery-late to form a copolymer of β-propiolactone and ethylene oxide. The structure and molecular weight of the copolymer were determined by element analysis, IR, NMR, VPO. The mechanism of this reaction is also discussed.
