| 摘 要： | 采用广角Ｘ射线衍射（ＷＡＸＤ）和差示扫描量热法（ＤＳＣ），研究了固相接板反应对聚丙烯晶态结构和热行为的影响。结果表明，聚丙烯用马来酸酐固相接枝后，晶面间距基本不变，微晶尺寸增大，熔点降低，结晶度略有提高。

| Abstract: | The effect of solid phase graft copolymerization on crystal structure and thermal behaviour of polypropylene was studied by WAXD and DSC method. The results show that the crystallite sizes of polypropylene increase due to the solid phase graft copolymerization of maleic anhydride,but the crystallographic interplanar spacing invaries,moreover,the melting point of modified polypropylene depresses,and its crystallity slightly increases. |
