本实验研究的目的是获得一些新的信息，热塑性聚合物的塑化水。采用差示扫描量热法研究了水分对聚对苯二甲酸乙二酯（PET）热性能的影响。通过以不同速率加热PET薄膜样品，测定了热动力学参数如玻璃化转变表观活化能、结晶表观活化能、Avrami指数和加热函数与聚合物含水量的关系。
The objective of this experimental study is to obtain some new information on the plasticization of thermoplastic polymers by water. The effect of moisture on the poly(ethylene terephtalate) (PET) thermal properties has been investigated using differential scanning calorimetry. By heating PET film samples at different rates, thermokinetic parameters such as the apparent activation energy for glass transition, the apparent activation energy, Avrami exponent and heating function for crystallization, have been determined in relation to the polymer water content.
