摘要

A new epxoy resin containing the pyrene moiety in the backbone (3) was synthesized and confirmed by gel permeation chromatography and field-desorption mass spectroscopy and infrared spectroscopy. In addition, to evaluate the influence of the pyrene moiety on the structure, epoxy resins having an anthylene moiety(5) and having a phenylene moiety(7) were synthesized. The cured polymer obtained through the curing reaction between 3 and phenol novolac was used for making a comparison of its thermal properties with those obtained from 5,7, and bisphenol-A (4,4'-isopropyli-denediphenyl)-type epoxy resin (Bis-EA). The cured polymer obtained from 3 showed a high glass transition temperature, lower coefficient of linear thermal expansion, lower moisture absorption, and markedly higher anearobic char yield at 700degC of 37.6 wt%. which might be attibuted to the hgiher aromaticity of 3 containing the pyrene moiety.
