摘要(Abstract)：

采用差示扫描量热仪及热重分析仪对PET/BaSO4共混聚酯的热性能进行了研究。结果表明:硫酸钡质量分数在0%～0.052%范围内时,其含量对共混体系的Tg及熔点无较大影响;但共混体系的冷结晶温度(T)c和冷结晶放热焓值均随BaSO4含量增加呈缓慢升高趋势,当BaSO4含量为0.052%时,共混体系冷结晶放热焓增加了近20%;随着BaSO4含量的增加,各体系的热稳定性逐渐升高,当BaSO4质量含量为0.052%时,体系热解活化能提高了35%。
The thermal properties of PET/BaSO4 were studied with DSC and TG. The results showed that BaSO4 contents had little influence on the glass transition temperature(Tg) and melting temperature(Tm ), the cooling crystallization temperature (Tc ) and the enthalpy of cooling crystallinity increased with the BaSO4 contents increasing. The cooling crystallinity increased by 20 % when the BaSO4 contents was 0.052 %. The heat stability of blend also increased with rising the BaSO4 contents, and the heat stability increased by 35 % when the BaSO4 contents was 0.052 %.
