摘要
通过红外光谱 (FT IR)、X 射线衍射 ,DSC及偏光显微镜等手段研究固相力化学方法制备的聚丙烯(PP) /N羟甲基丙烯酰胺 (HMA)接枝共聚物 (PP g HMA)的微观结构 .结果表明 ,应力作用使聚丙烯的微晶尺寸变小 。
The microstructure of polypropylene grafting hydroxymethyl acrylamide (PPgHMA), which was prepared by employing our selfdesigned pan type milling equipment to panmill the mixture of PP particle and HMA, was investigated by FTIR, Xray diffraction analysis, DSC and polar optical analysis. The results showed that size of PP spherulites decreased under stress and the crystallinity of PPgHMA decreased as compared with PP due to HMA onto PP.
