甲基丙烯酸甲酯-苯乙烯无规共聚物与聚偏氟乙烯共混体系的结晶行为和力学性能

STUDY ON THE CRYSTALLIZATION BEHAVIORS AND MECHANICAL PROPERTIES OF POLY (VINYL IDENE FLUORIDE) AND METHYL METHACRYLATE- STYRENE RANDOM COPOLYMER

本文研究了甲基丙烯酸甲酯-苯乙烯(MS)无规共聚物与聚偏氟乙烯(PVF_2)共混体系的结晶行为和力学性能。MS含量及MS中St的含量均对PVF_2的结晶行为有较大的影响,它显示出非晶材料向结晶材料转变过程中所特有的力学性质不连续现象。研究结果表明了PVF_2/MS共混物作为一种改性材料应用的可能性。

The blends of poly(vinylidene fluoride) (PVF2)and methyl methacrylate-styrene random copolymer (MS) of different styrene (St) mol% were investigated.This paper deals with the miscibility of PVFz/MS blends by differental scanning catori-meter, scanning electron microscope and cloud point measurement.The LCST curve of the blends was also determined.
