摘要
综述了聚合物接枝改性的几种常见方法,如溶液接枝聚合、悬浮接枝聚合、超声波引发接枝聚合、超临界流体技术引发接枝聚合等,介绍了接枝聚合原理、研究和应用,并总结了接枝改性聚合物接枝率的表征方法,包括酸碱滴定法、傅里叶红外光谱(FTIR)、X射线衍射图谱分析(XRD)和元素分析法等。
Grafting modifications of polymers by solution graft polymerization, suspension graft polymerization, ultrasonic and snpercritieal fluid techniques were reviewed, additionally, the principles, researches, and their applications were briefly introduced. At the same time, characterizations, including acid-base titration, Fourier transform infrared spectrometer（FTIR）, X-ray diffraction（XRD） and elemental analysis（EA）, for graft ratio of the grafted polymers were systematically summarized.
