摘要：

Chemical modification of poly (epichlorohydrin) (PECH) with nadimide derivatives using 1,8-diazabicyclo (5.4.0)-7 undecene to catalyze the substitution of the chlorine atom by acid compounds (DBU method) was accomplished. The linear polyethers obtained showed a degree of substitution from 5-80%, depending on time and temperature reaction. The T(g) of modified polymers and Ea, calculated in the cure reactions, increases with substitution degree. Residual enthalpies were observed in all cases, which suggests that the curing reaction is incomplete. TGA measurements showed that the degradation has a greater dependence on the modification degree than on the introduced pendant group. (C) 1994 John Wiley & Sons, Inc.
