对纯环氧树脂及其与膨胀性单体NSOC 共聚得的收缩、或等密度、或膨胀的共聚环氧树脂试样作了应力-应变实验和动态力学试验。由于NSOC 的引入,树脂的强度和玻璃化温度均下降,表明分子链结构对性能的影响超过聚合时体积膨胀引起的效应。
The stress-strain curves and dynamic mechanical properties ofpure epoxy resin and epoxy copolymer with shrinkage or equal-density or exp-ansion obtained by copolymerizing epoxy resin with various amounts of expan-ding monomer NSOC have been measured.The b
