摘要
PBT/PET共混体系是一种结晶/结晶聚合物共混体系,除熔融状态外,通过骤冷或其他处理,还可得到玻璃体等非结晶态。本文研究它们处于非结晶态的相溶性问题,用动态粘弹谱仪、差示扫描量热等进行考察,取得处于非晶状态下的PBT/PET体系彼此相溶的实验判据。
The compatibilty of the blends PBT/PET have been studied by DSC andviscoelastometer. It has been confirmed that: the blends of PBT and PET are com-patible in amorphoud region, because only one glass transition temperature (Tg) hasbeen observed in their DSC curves and dynamic mechanical spectra.
