摘要
用示差量热法(DSC)、动态力学分析法(DMA)和悬浮法测密度法研究了聚偏氟乙烯(PVF_2)/甲基丙烯酸甲酯与苯乙烯的无规共聚物[P(MMA-St)]的共混体系的相容性和结晶性能。结果发现PVF_2/P(MMA-St)共混体系是部分相容体系,其结晶性能随共混物中P(MMA-St)的含量而变化,并就模压成型的热历史对该共混体系相容性的影响进行了讨论。
By DSC, DMA and density measurement, the crystallinity and compatibility of polyvinylidene fluoride/ random copolymer of methyl methacrylate and styrene [PVF2/P(MMa - St)] were studied. It was found that PVF2/P(MMA-St) blend was partially compatible, its crystallinity varied with the content of PVF2/P(MMA - St). The influence of thermo - history of moulding on compatibility of the blend was discussed.
