The preparation of PP grafted with MAA in solid phase and its grafting with PA6

The polypropylene (PP) grafted with methacrylic acid (MAA) in solid phase was prepared, and the resultant PP - g - MAA was characterized by infra - red spectroscopy. Furthermore, the anionic grafting of polyamide 6 (PA6) was carried out with the resultant of the reaction between the carboxyl in the grafted side chain of the PP -g - MAA and 2, 4 - toluene diisocyanate. Consequently, a kind of graft polymer of PP and PA was successfully prepared via the anionic polymerization process. The structure of the PP - g - PA6 was verified by infra - red spectroscopy and differential scanning calorimetry.
