摘要： 本工作用应力松弛仪测定了一组等支链长不同支化度星形聚苯乙烯的松弛谱,探讨了支化结构对松弛谱橡胶平台区粘弹行为的影响,用“管子”模型对松弛谱进行了计算机模拟,从分子运动观点上解释了星形聚合物的粘弹特性.
关键词: 星形聚苯乙烯, 粘弹性, 力学松弛
Abstract: The relaxation spectra of a set of star-shaped polystyrenes with the equal length of arms but different branching degree were determined by means of a stress relaxation instrument.The effect of branching structure on the rubbery plateau in the relaxation spectra was investigated,and the relaxation spectra were computer simulated using a"tube"model.The difference in viscoelastic properties of star-shaped polystyrenes were interpreted in terms of molecular motion.
Key words: Star-shaped polystyrene, Viscoelasticity, Mechanical relaxation
