摘要
In this paper, the modification of polypropylene (PP) with acrylic acid (AA) by reactive extrusion using pre-irradiated PP (rPP) as initiator was investigated. It was found the relatively high graft degree (Gd) and slight degradation of modified PP was obtained when 20 wt% rPP was used. This result can be explained in terms of effective concentration of free radicals. Compared with the neat PP, the modified PP showed the high-notched impact strength and improved adhesion of PP to polar substrate. This technique is of potential industrial interest for PP modification.
