丙烯酸钠离聚物与聚乙二醇复合对结晶行为的影响

摘要/Abstract

摘要：

利用差示扫描量热仪(DSC)研究了离聚物苯乙烯-丙烯酸钠(SAA-Na)和聚乙二醇(PEG)复配物对PET结晶性能的影响。结果表明，1%（质量分数）SAA-Na与5%PEG复配能够进一步提高PET的结晶速率，使熔融结晶温度由PET/SAA-Na的212.8℃升高到<

Abstract:

The crystallization of PET modified by the mixture of styrene-sodium acrylate ionomer (SAA-Na）and poly(ethylene glycol）（PEG）was investigated by differential scanning calorimeter(DSC).With the addition of 5%（mass） PEG, cold-crystallization temperature (T_cc）and glass transition temperature (T_g）of PET decreased significantly.Compared with PET/SAA-Na, the crystallization of PET/mixture (1%SAA-Na and 5%PEG）was further enhanced,melt-crystallization temperature (T_mc）increased from 212.8℃ to 216.1
