Graft copolymer of acrylic acid (AA) onto styrene-butadiene-styrene (SBS) block copolymer was synthesized by using benzoyl peroxide (BPO) as initiator , toluene as solvent Its structure of graft reaction were investigated with infrared spectrum .

• 以过氧化苯甲酰(BPO)为引发剂,甲苯为溶剂,进行了丙烯酸(AA)与SBR的接枝共聚反应,合成了主链为SBS,支链为聚丙烯酸(PAA)的接枝共聚物(SBS-g-AA)。 其结构已被红外光谱分析所证实。
