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。
The graft copolymerization of maleic anhydride grafted polypropylene (PP-g-MAH) with styrene (St) and butyl acrylate (BA) Effect of surface properties. The results showed that the surface energy and the polar component of PP-g-MAH firstly and then decreased with the increase of the amount of xylene. The surface energy (37.52 mN / m) and polar component (2.47 mN / m), respectively. The addition of comonomer St, BA can significantly increase the surface energy and polar force components of PP-g-MAH. The effect of comonomer St To be effective, the polar components of their grafts are 2 times that of PP-g- (MAH-co-BA) and 4.8 times that of PP-g-MAH, respectively.
