摘　　要：在实验测得高压环境中PET玻璃化转变温度(Tg)的基础上,将所得实验数据与G-D,CHOW等理论模型计算的Tg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.
