Abstract
Solid phase graft of maleic anhydride onto polypropylene in helical ribbon reactor is performed and the influ encing processing parameters influencing the graft ratio are investigated. 5 % graft ratio of polypropylene is obtained with polypropylene powder,anhydride benzoyl peroxide as initiator and 5 % catalyst addition at agitation speed 160 r/ min and reaction time 80 min.
