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 (Tcc）and glass transition temperature (Tg）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 (Tmc）increased from 212.8℃ to 216.1
