乳聚三元共聚橡胶的制备及单体配比对聚合物结构和性能的影响

Preparation of ter-polymerized rubber by emulsion polymerization and effect of monomer ratio on properties of the product

通过乳液聚合合成了苯乙烯-异戊二烯-丁二烯三元集成橡胶(E-SIBR),通过红外和核磁测试对产品进行表征,并详细研究了聚合过程中单体配比的变化对聚合物微观结构单元组成、相对分子质量分布、玻璃化转变温度以及物理机械性能的影响。

Styrene-butadiene-isoprene rubber was prepared by emulsion polymerization and characterized through IR、HNMR and DMA.Effects of monomer ratio on the micro-structure,the glass-transition temperature,the molecular weight distribution and the mechanical properties of the product were discussed in detail.
