摘　　要：综述了近年来制备丙烯-苯乙烯接枝共聚物(PP-g-PS)(PP表示聚丙烯、PS表示聚苯乙烯)的研究进展。PP-g-PS的制备方法包括熔融接枝法、固相接枝法、Hivalloy合金技术、辐射接枝法、反应性单体法和大分子单体法。前3种方法得到的均是PP/PP-g-PS/PS共混物;辐射接枝法仅适用于PP的表面改性;PS大分子单体的空间位阻大,在共聚物中的含量较低;反应性单体法是一种很有工业应用前景的方法,可通过活性接枝共聚合反应,得到支链长度和接枝点密度可控的PP-g-PS。Recent developments on synthesis of polypropylene - g - polystyrene （ PP - g - PS） were reviewed, including melt - grafting, solid - phase grafting, Hivalloy technology, radiation - induced grafting, reactive monomer method and PS macromonomer method. PP/PP -g -PS/PS blends can be prepared by the first three methods. Radiation - induced grafting method is favorable to modify PP particle surface. As for PS macromonomer method, probability of macromonomer incorporation is very low due to its steric hindrance. Reactive monomer method is a promising route for industrial application, and well - controlled and well - defined PP - g - PS can be synthesized via living graft copolymerization by this method.
