熔融法制得PP-g-HEMA性能的研究

Study on Properties of PP-g-HEMA Prepared by Melt Graft Copolymerization

由熔融法制得聚丙烯接枝甲基丙烯酸β－羟乙酯，用毛细管流变仪、示差扫描量热计、广角Ｘ－射线衍射仪、结晶速率仪、偏光显微镜等对接枝物的流变性能和结晶性能进行了定性、定量表征，比较了接枝前后聚合物结晶形态的变化。

PP-g-HEMA was prepared utilizing the technique of melt graft copolymerization. The rheological behaviour and crystal properties of the grafted copolymer were studied by capillary rheometer、DSC、WAXD、crystal growth speedmeter and crossed polarizing microscope. The crystal morphology of grafted and ungrafted PP was compared.
