The low molar mass PPE/ TAIC blends were shown to have the upper critical solution temperature
(UCST) type phase behavior , and cloud point curves intersect the glass t ransition2composition lines at a PPE con2
tent of about 50 %. Phase behavior and cure behavior were investigated by different techniques : light t ransmission
measurement s , fourier2t ransform inf rared spect rometer , and different scanning calorimeter. The cured morphology
of the PPE/ TAIC blends was studied by atomic force microscope. With increasing PPE content for PPE/ TAIC
blends , the diameter of the dispersed PPE particles has a significant increase , and the thermal stability of the blends
is also increased. The cured PPE/ TAIC systems exhibit good chemical resistance and thermal stability.
