摘要
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。接枝共聚反应配方及条件为:AA用量250g/L,BPO用量2.4×10^(-2)mol/L,70—80℃,4h。与PAA/SBS共混物胶膜相比,SBS-g-AA胶膜具有较好的透明性和内聚强度。
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 . The graft reaction conditions were : AA amount 250 g/L , BPO amount 2.4 × 10-2 mol/ L, 70- 80°C ,4 h . As compared with PAA/SBS blend , graft copolymer SBS-g-AA had better transparance and cohesive strength .
