Maleicanhydride grafted natural rubber (MNR) was used as modifier, and its effect on the mechanical properties and thermal property of waste newspaper flour (PF) filled PVC composites was studied.
A series of aqueous polyurethane dispersions (MCPU) with ionic groups in the soft segments were prepared with maleicanhydride modified castor oil (MCO) of various hydroxyl functionality.
The preparation process of maleicanhydride grafted polypropylene (PPg-MAH) was studied by reactive extrusion using a twin screw extruder system and infrared spectroscopy.
