Synthesis and characterization of high‐density polypropylene .

High‐density polyethylene grafted isotactic polypropylene (PP‐ g ‐HDPE) was prepared by the imidization reaction between maleic anhydride grafted polyethylene and amine‐grafted polypropylene in a xylene solution. The branch density was adjusted by changes in the molar ratio between maleic anhydride and primary amine groups.
