Modification of low molecular weight polyethylene with maleic anhydride and chitosan

Modification of lowmolecularweight polyethylene with maleic anhydride and synthesis of grafted copolymer of low-molecularweight polyethylene with maleic anhydride and chitosan in melt using radical polymerization initiator were carried out under shear field conditions. The fact of copolymer formation was confirmed by elemental analysis and IR spectroscopy data. The synthesized copolymers can be used to obtain compositions of polyethylene with chitosan. Their presence contributes to an increase in the melt flow index, which leads to an improved distribution of particles of dispersed phase in the composition and manufacturability of its processing.
