| 摘 要： | 采用固相接枝方法,研究了以二甲苯为界面剂,以苯乙烯(St)、丙烯酸丁酯(BA)为接枝共聚单体对马来酸酐接枝聚丙烯(PP-g-MAH)表面性能的影响。研究结果表明,随着二甲苯用量的增加,PP- g-MAH的表面能和极性力分量呈先升后降的趋势,当w(二甲苯)=15%时,表面能(37.52 mN/m)和极性力分量(2.47 mN/m)均达到最大值;共聚单体St、BA的加入可以显著提高PP-g-MAH的表面能和极性力分量,共聚单体St的作用更为有效,其接枝物的极性力分量分别是PP-g-(MAH-co-BA)的2倍,PP- g-MAH的4.8倍。

| Abstract: | The influences of xylene,styrene(St) and butyl acrylate(BA) on the surface performance of polypropylene grafted by maleic anhydride(PP-g-MAH) were studied by solid-phase graft copolymerization with xylene as interfacial agent,and St and BA as graft comonomer.The research results showed that the surface energy and polar component of PP-g-MAH had trend of rise-fall with the increase of xylene content,the surface energy (37.52 mN/m) and polar component(2.47 mN/m) were all maximum value when mass fraction of xy... |
