Abstract
4,4'-biphenyl diglycidyl ether was synthesized from 4,4'-biphenol and epichlorohydrin by two-step method.Effects of catalyst,epichlorohydrin and base on synthesized 4,4'-biphenyl diglycidyl ether were investigate.The optimum process was that n(4,4'-biphenol):n(epichlorohydrin)=1:16 and n(4,4'-biphenol):n(NaOH)=1:3.0.The structure of the epoxy resin was characterized by FT-IR and 1HNMR.The molecular weight was analysed by mass spectrometry,the physical and chemical properties of product was determinated.The result showed as followed:molecular weight of the product 299.1,epoxide number 0.65-0.67,organic chloride content40 mg/100 g,inorganic chloride content20 mg/100 g and the process of thawing was 159.1-160.4.
