摘要：

The cure and transitions of a C10 diamide phthalocyanine resin have been investigated by the torsional braid method. Two relaxations (T′ > Tg and T > Tg) occurring above the glass transition temperature (Tg) are shown to correspond to two relaxations which develop prior to vitrification on isothermal cure. They bear directly on processibility of the material. Also investigated was the coupling between a low temperature transition (∼ − 146°C/2.1 Hz) inherent to the material and a low temperature water‐induced transition (∼ − 76°C/1.9 Hz).
