PVC/低熔点尼龙6共混物力学性能的研究

Study on Mechanical Properties of Blends of PVC and Low Melting-point PA6

采用(苯乙烯/马来酸酐)无规共聚物(R-SMA)为增容剂制备低熔点尼龙6(uPA6)与PVC共混材料,研究了SMA和uPA6的加入量对PVC/uPA6共混物力学性能的影响。结果表明,SMA是PVC/uPA6体系的有效增容剂,SMA的加入能使uPA6在PVC中的分散相尺寸降低,大幅度提高PVC/uPA6的力学性能。

Blends of poly （Vinyl Chloride） （PVC） and low melting- point PA6 （uPA6） using a reactive eopolymer styrene - maleie anhydride （SMA - 18 % ） were prepared in this paper. The effeet of SMA and uPA6 concentration on morphology and meehanieal properties of the blends was discussed. The experimental results show that SMA is an effective eompatibilizer to PVC/uPA6 blends and can deerease the partiele size of uPA6 on continuous phase of PVC, and thus enhanee the meehanieal property of PVC obviously.
