摘要

本文在苯乙烯-丁二烯-苯乙烯嵌段共聚物 (Styrene-Butadiene-Styrene triblock copolymer, SBS) 辐射接枝马来酸酐（Maleic anhydride, MAH）的基础上，进行MAH/苯乙烯 (Styrene, St)二元单体辐射接枝研究，讨论了MAH /St比例和总浓度及吸收剂量对接枝率的影响。就MAH接枝产物SBS-g-MAH和MAH/St二元接枝产物SBS-g-MAH/St进行了傅立叶红外光谱（Fourier transform infrared spectroscopy, FTIR）、热重（Thermal gravimetric, TG）分析与差示扫描量热（Differential scanning calorimetry, DSC）分析等表征与分析。结果表明：MAH/St二元接枝可明显提高MAH接枝率。

Abstract

Based on studies at SINAP on radiation-induced graft copolymerization of styrene-butadiene-styrene (SBS) copolymer with maleic anhydride (MAH), Maleic anhydride/styrene (MAH/St) binary monomers system grafting onto SBS was investigated. Effects of the comonomer composition, concentration and irradiation dose were studied. The graft copolymer was characterized by Fourier-transform infrared, thermogravimetric analysis and differential scanning calorimetry. The results showed that binary graft could increased the grafting yield of MAH.
