Volume shrinkage of sample results in the increasing of the value of the crystallization rate vc and the decreasing the values of the avrami exponent n in the primary crystallization and s , defined as the relative crystallinity degree when experiment data deviate theoretical predicting straight line . compared with the avrami equation , the price equation hardly makes progress on describing the behavior of polymer later stage crystallization 樣品體積收縮,導致avrami指數(shù)n值減??;結(jié)晶速度v _ c值增加;表示實驗值偏離理論預測直線時的相對結(jié)晶度_ s值減小;與avrami方程相比, price方程仍不能較準確地描述高聚物等溫后期結(jié)晶行為。
