摘要

Fourier transform infrared spectroscopy (FTIR) was used to follow the curing of the diglycidylether of bisphenol A(DGEBA) typical epoxide resin by poly(sty-rene-alt-maleic anhydride)(AMS),the reaction being accelerated by triethylamine(TEA) in the pressence of methanol.The study was done in an isothermal mode for four temperatures:85,82,80,and 75degC.We followed,for each temperature,the variation of the area of the opoxy band (916 cm~(-1)) versus time.After 200 min of reaction,the degree of conversion of epoxy is 0.5 at 85degC.A postcure at 100degC during 96 h allows one to reach a total conversion of epoxy.The reaction mechanism involves three steps to form the tridimensional network.
