综述了玻璃-橡胶过渡区附近无定形聚合物粘弹性的流变光学研究。重要进展之一是发现了改进的应力光学规则 MSOR。该规则表明，压力有两个分子起源。一种（R 成分）是由于像橡胶材料一样的链取向，另一种（G 成分）是由于重复单元堆积状态的变形。 G组分具有玻璃成型材料的共同特征。 MSOR 成功解释了玻璃化转变区周围粘弹性的许多特征，例如时间-温度叠加原理的崩溃。另一个意义是MSOR提供了一种分析玻璃化转变区周围粘弹性的新方法。两个起源的分离为粘弹性与分子结构之间的关系提供了更好的前景。该方法可应用于其他重要问题，包括玻璃化转变区周围的非线性粘弹性和玻璃态区的亚松弛。
Rheo-optical studies on viscoelasticity of amorphous polymers in the vicinity of the glass-to-rubber transition zone are reviewed. One of important progresses is a finding of the modified stress-optical rule, MSOR. The rule says that the stress has two molecular origins. One (R component) is due to the chain orientation like rubbery materials and the other (G component) is due to deformation of packing state of repeating units. The G component has common features for glass forming materials. The MSOR successfully explains many characteristic features of the viscoelasticity around the glass transition zone such as breakdown of time-temperature superposition principle. Another significance is that the MSOR provides a new method to analyze the viscoelasticity around the glass transition zone. The separation into the two origins gives better prospects on the relationship between viscoelasticity and the molecular structure. The method can be applied to other important issues including nonlinear viscoelasticity around the glass transition zone and sub-relaxations in the glassy zone.
