ABS/PET合金的相容化研究

Study on the Compatibility of ABS /PET Alloy

以苯乙烯-丙烯腈-甲基丙烯酸缩水甘油酯(SAG)和苯乙烯-丙烯腈-马来酸酐(SMA)为相容剂对丙烯腈-丁二烯-苯乙烯(ABS)/聚对苯二甲酸乙二醇酯(PET)合金进行增容。并从拉伸性能、弯曲性能、冲击性能、熔体质量流动速率(MFR)等方面对SAG和SMA的增容效果进行了比较。结果表明,含有GMA基团的SAG比含有MAH基团的SAM的增容效果更好。

Acrylonitrile butadiene styrene （ABS）/polyester terephthalate （PET） blends were compatibilized with styrene-acrylonitrile-maleic anhydride （MAH） copolymer and styrene-acrylonitrileglycidyl methacrylate （SAG） copolymer as compatilizers.The compatibilizing effects were compared between SAG and SAM by the results of tensile strength,bending strength,impact strength and melting flow rate （MFR）.It was concluded that the compatibility of SAG with GMA functional group was better than that of SMA with MAH functional group.
