摘　　要：采用溶液聚合法合成了几种不同接枝率的丙烯酸酯改性CPP(氯化聚丙烯)。研究了CPP及改性CPP的稀释比、溶度参数和相对溶解度。试验结果表明:改性CPP的极性随着接枝率的增大而增加,相对溶解度在中等氢键力溶剂中也随接枝率的增大而增加,而在弱氢键力和强氢键力溶剂中没有明显变化。Several acrylate modified chlorinated polypropylene （ CPP ）with different grafting rate were synthesized by solution polymerization method. The dilution ratio, solubility parameter and relative solubility of CPP and modified CPP were studied. The test results indicated that the polarity of modified CPP increased with the grafting rate, which would cause increment for the relative solubility in the moderate hydrogen bonded solvents, whereas there was not any clear change in that of poor and strong hydrogen bonded solvents.
