通过优化条件的酸性水解法合成了八乙烯基倍半硅氧烷(OVS),用红外光谱(FT-IR)及1H核磁共振(1H NMR)对产物进行了表征.结果表明,优化的反应条件能够缩短OVS合成时间.采用悬浮聚合法制备了八乙烯基倍半硅氧烷/丁苯橡胶(OVS/SBR)吸油材料.热重分析(TG)发现OVS/SBR相对于SBR有更好的热稳定性,扫描电镜(SEM)图像发现OVS/SBR断面具有多孔结构,FT-IR分析发现OVS在SBR中以笼型结构存在.实验探究了交联剂OVS、引发剂过氧化苯甲酰(BPO)、制孔剂聚乙二醇(PEG)和反应时间对材料吸油倍率的影响,结果表明OVS 0.8％、BPO 1.0％、PEG 16 g/10 g SBR、75℃反应6h时,材料对二甲苯吸收倍率有最大值38.0 g/g.OVS/SBR材料油水共存环境测试表明其具有良好的物理稳定性.
