【摘要】 <正> 一、前言聚丙烯酸环氧酯可以看作是环氧树脂与聚丙烯酸酯树脂的“杂交”产物,因而它综合了这两类树脂的特点。从丙烯酸环氧酯的化学结构看,它既含有环氧树脂固化后的结构单元二甘油基双酚A,又含有酯键与乙烯更多还原

【Abstract】 On the base of poly(acrylic epoxyester)F-grade solventless varnish,a solvent-based modified poly(ac-rylic epoxy ester) F-grade impre-gnating varnish was prepared bythe copolymerization of aromaticheterocyclic thermosetting resin andacrylic epoxy ester. It eliminatesthe imperfections of the solventlessimpregnating paint and improve thethermal stability of the resin.更多还原
