Abstract

Dissipative processes in highly elastic latex polymers have been analyzed based on a theoretical calculation of the relaxation microheterogeneity of polymer structures. The microheterogeneity is evaluated graphically from the dependence of the dissipation intensity ratio λ/λmax on the temperature ratio (ТТmax)/Тmax. The α-relaxation intensity is determined using the internal friction spectrum recorded by dynamic relaxation spectroscopy.

丙烯酸乳胶聚合物中弛豫过程的理论分析

摘要

基于聚合物结构的弛豫微异质性的理论计算,对高弹性胶乳聚合物中的耗散过程进行了分析。的微观不均一从耗散强度比的依赖性图形评价λ/λ最大的温度比(Т - Т最大值)/ Т最大。α松弛强度是使用由动态弛豫光谱法记录的内部摩擦谱来确定的。
