在实验测得高压环境中PET玻璃化转变温度(您)的基础上,将所得实验数据与G—D,CHOW等理论模型计算的%值进行验算比较,发现两种模型均不能很好的描述高压条件下CO2对PET的溶胀行为。
The experimental data ( PET glass transition temperature (Tg) ) obtained under high - pressure condition were compared with the theoretical model G - D, CHOW. It was found that the predictions of these two model were not in good agreement with the experiment.
