采用等规聚丙烯与马来酸酐的固相接枝法，制得具有不同酸值的马来酸酐接技改性的聚丙烯树脂（ＰＰ－ｇ－ＭＡ）。研究了其涂层性能。并将ＰＰ－ｇ－ＭＡ－与环氧－聚酯粉末涂料共混，研究了共混物涂层性能。试验结果表明，ＰＰ－ｇ－ＭＡ本身或其与环氧－聚酯粉末涂料的共混物均具有良好的涂层性能，两者的协同作用明显。
Maleic anhydride graft modified polypropylene resin (PP-g-MA) with different acid value was prepared by solid phase grafting of isotactic polypropylene with maleic anhydride. The coating properties were studied. The PP-g-MA- and epoxy-polyester powder coatings were blended to study the coating properties. The experimental results show that PP-g-MA itself or its blends with epoxy-polyester powder coatings have good coating properties, the synergy between the two obvious.
