The convenient adhesive with good properties for polypropylene foam material was prepared here, based on graft polymer from chlorinated polyethylene and maleic anhydride.

The preparation process of maleic anhydride grafted polypropylene (PPg-MAH) was studied by reactive extrusion using a twin screw extruder system and infrared spectroscopy.

The graft recipe of maleic anhydride (MAH) onto PP was studied, and the decomposition inhibition method on PP radical during grafting reaction process was explored.
