| 摘 要： | 以过氧化二异丙苯（DCP）为引发剂。在转矩流变仪中将甲基丙烯酸（MAA）熔融接枝到ABS树脂。纯化后样品的红外光谱分析表明。MAA接枝ABS产物在1721．67cm^-1处出现了C=O基吸收峰，证实MAA已成功地接枝到ABS树脂上。实验研究单体用量、引发剂用量、螺杆转速和反应温度对接枝率的影响。结果表明：接枝率随引发剂用量、反应时间以及反应温度的增加而增大，随单体用量的增加呈现先增后降的趋势。将ABS-g-MAA接枝物应用于ABS／膨胀型阻燃剂（IFR）／蒙脱土（MMT）无卤阻燃体系中．可以有效改善复合材料的力学性能。

| Abstract: | This paper reports the experimental study of melt grafting the methacrylic acid(MAA) is onto the acrylonitrile-butadiene-styrene terpolymer(ABS) backbone by dicumyl peroxide(DCP) in the RM-200 Rheometer. The infrared spectra results confirm the successfulness of the grafting.The influences of monomer amount,DCP amount,reaction temperature,and the screw rotating velocity on grafting degree are investigated.It reveals that the grafting degree is increased with the increase of DCP amount,reaction time,and reaction temperature.It is increased at first and then decreased with the increase of monomer amount.The mechanical property of the halogen-free flame retardant ABS/IFR/MMT composites is improved significantly by adding ABS-g-MAA. |
