1·According to the molecule design, a kind of modified resin which have both epoxy groups and hydrophilic groups was synthesized from polyfunctional group novolac epoxy resin (F-51) and diethanolamine.

采用化学改性法，选择多官能团酚醛环氧树脂(F—51)与二乙醇胺进行定量加成反应，合成了一种在分子结构上既具有环氧基团，又具有亲水性基团的改性树脂。

2·There are a lot of studies on modification of epoxy with silicone domestic and abroad, but few studies on modification of novolac with silicone are searched.

国内外对有机硅改性环氧树脂进行了大量的研究，但对有机硅改性酚醛环氧树脂的研究较少。

3·The content of the hydrolyzable chlorine ino -cresol -novolac epoxy resin (ECN) is an important factor which influences the quality of the resin.

ECN树脂中的可水解氯含量是决定树脂质量的—个重要指标。

4·Dicyanate/novolac epoxy matrix was developed for hot-melt fiber winding process.
