In this paper , glycidyl ether , which was high epoxide value and low viscosity , was synthesized from 2 - trimethylene glycol , epichlorohydrin and the normal butyl alcohol by phase transfer catalyst based on the orthogonal experiment design 摘要采用1 , 2 -丙二醇、正丁醇和环氧氯丙烷为原料，在相转移催化剂的作用下反应，通过正交实验合成了的高环氧值、低粘度的混合醇缩水甘油醚。
Abstract ： this assay initially discussed the researches and developments of syntheses and reforming of the tetratlycidyletyer of tetraphenol ethane applying to the copper clad laminate and simply explained its principles and functions of uv - ray shield and fluorescence 摘要：本文对四官能环氧树脂[ 1 ， 1 ， 2 ， 2 ?四（对羟基苯基）乙烷四缩水甘油醚]的合成与改性及在覆铜板中的应用作了初步探讨，并对其屏蔽紫外线与产生荧光的机理作用作粗浅的阐述。
Six different molecular weigh polyethylene glycols were selected to prepare blend films with silk fibroin , five different molecular weight polymer - polyethylene glycol diglycidyl ether ( pego ) were synthesized and structures of them were characterized by 1h nmr , ir , gpc . a kind of silk fibroin membranes were prepared by blend the pego and silk fibroin 选用六种不同分子量的聚乙二醇与丝素共混制膜，并选用其中五种合成了五种不同分子量的聚乙二醇缩水甘油醚( pego ) ，以合成的pego为添加剂，研究了不同分子量、不同含量下制得的改性丝素膜的结构与性能。
