摘要

压力加速了整个等温固化反应。凝胶化和玻璃化在压力作用下发生改变。在常压下测得的压力固化样品的玻璃化转变温度提高了约10℃。这可能是由于压力固化样品中凝胶相交联密度的增加。

Effects of hydrostatic pressure on isothermal curing of an epoxy resin–amine system
Overall isothermal curing reaction is accelerated by pressure. The gelification and vitrification is modifying by the pressure. The glass transition temperature of pressure-cured samples measured at atmospheric pressure increases by about 10°C. This is probably due to increase in the crosslink density of the gel phase in pressure-cured samples.
