摘　　要：采用熔融法制备C5石油树脂接枝马来酸酐(C5-g-MAH),研究了过氧化二异丙苯(DCP)、马来酸酐(MAH)用量和第三组分(助交联剂)品种对C5-g-MAH接枝率的影响。研究结果表明,DCP用量为0.2份,MAH用量为4份时接枝率最大,为1.28%;第三组分品种对C5-g-MAH接枝率的影响从大到小依次为:腰果壳油、三烯丙基异三聚氰酸酯(TAIC)、1,2-聚丁二烯(1,2-PBd),均比空白样有所提高。此外,傅立叶红外光谱(FT-IR)分析证实发生了MAH熔融接枝C5石油树脂的接枝反应。The melt grafting of maleic anhydride（MAH）onto C5 Petroleum resin was initiated in a twin screw extruder at 110～120 ℃.The influence of peroxide diisopropylamine benzene（DCP）,maleic anhydride（MAH） and the third component on the melt grafting behavior was studied.It was found that the C5-g-MAH has the maximum value of the grafting degree 1.28% when adding 0.2 phr DCP and 4 phr MAH.As the third monomer,the influence of the value of grafting degree from large to small is as follow：cashew nut shell oil（CNSL）,triallyl isocyanurate（TAIC）,1,2-polybutadiene（1,2-PBd）,and all have better performance than blank samples.The fourier transform infrared spectroscopy（FT-IR）spectra showed MAH was successfully grafted onto C5 petroleum resin.
