Efficient approach to produce functional polypropylene via solvent assisted solid-phase free radical grafting of multi-monomers

Abstract Herein an efficient approach to produce functional polypropylene via solvent assisted solid-phase grafting process is reported, in which acrylic acid, methyl methacrylate and maleic anhydride are used as multi-monomers, 2,2?-azobis(2-methylpropionitrile) initiator ether swelling carrier. The effects of various factors such the species dosage, time temperature, monomer concentrations, reaction nitrogen flow rate stirring speed on percentage efficiency were investigated. To verify polar was grafted onto polypropylene, resulted polymers characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction analysis, water contact angle measurement, tensile strength melt measurement. All results showed that using free radical versatile polypropylene.
