Grafting reactions were performed in a Haake torque rheometer, according to a central composite experimental design, where the maleic anhydride and peroxide concentrations, rotor speed, and reaction time were varied. The 27 formulations were analyzed by Fourier transformed infrared spectroscopy and
A monomer mixture of styrene (St) and maleic anhydride (MA) was grafted on isotactic polypropylene (PP) powder at 80Β°C in benzene. During that process ungrafted copolymer is formed at the same time. The initiators are peroxide groups formed on the surface of polypropylene (PP) by ozonization or by g
A~traet--Melt blends of polypropylene(PP)/nylon-6, PP/nylon-6/(maleic anhydride-g-polypropylene-(MAH-g-PP)) and (MAH-g-PP)/nylon-6 have been prepared using a Brabender plasticoder. Measured properties included steady shear viscosities from a capillary rheometer, thermal properties from DSC, and morp
