Solid Phase Graft of Maleic anhydride onto Polypropylene in Helical Ribbon Reactor

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.
