摘要： 利用吡啶改性丁苯橡胶(PSBR)乳液与正溴丙烷反应后生成PSBR季铵盐,再与铝酸酯、钛酸酯以及活性硅烷醇反应,制得有机-无机杂化弹性体PSBR胶片(PSBR-MnOm).经与天然橡胶并用,制成复合硫化胶.复合硫化胶的力学性能较好,并具有较高的滞后损耗.其压缩永久变形率与天然橡胶相似.用FTIR、高分辨NMR、DSC和TG等手段对其结构进行了分析,并认为在含有金属的复合硫化胶中可能存在"介稳巨大配合物",对其物理性能的增强起一定作用.

Abstract: Pyridinium salt was produced by using reaction of vinylpyridine-SBR(PSBR) latex with propyl bromide, and then it reacted with aluminum alkoxide, alkyl titanate and active silanol to prepare a organic/inorganic hybrid elastomer latex(PSBR-MnOm). Akind of composite vulcanizate was obtained after the hybrid elastomer was compounded with natural rubber. Its mechanical performance is rather good and its hysteresis loss is quite high. In addition, it is similar in compression set to NR. Its structure was analyzed by FTIR, high-resolution NMR, DSC and TGetc .. It is believed that the existence of "huge metastable complexes" in the metal-containing composite vulcanizate may improve its mechanical properties.

Key words: PSBR latex, Metal alkoxide, Hybrid elastomer, Mechanical performance, Structure analysis
