【摘 要】The relative molecular mass and its distribution and microstructure of the environmentally friendly styrene-butadiene rubber( SBR ) were compared with traditional SBR. The vulcanization characteristics of their compounds and mechanical and processing properties of their vulcanizates were also compared. The results showed that environmentally friendly SBR 1500 E and SBR 1500 had almost the same molecular structure, mechanical properties, relative molecular mass and its distribution.And so do the environmentally friendly SBR 1502 E and SBR 1502. The plastic properties of environmentally friendly SBR, which was easier processing ,were better than those of traditional SBR. Oil-filled environmentally friendly SBR 1723 had poor mechanical properties but a better plastic property.%对比考察了环保型丁苯橡胶与传统丁苯橡胶的相对分子质量及其分布、微观结构、混炼胶的硫化特性、硫化胶的物理机械性能及加工性能,结果表明,环保型丁苯橡胶SBR 1500 E与SBR 1500、环保型丁苯橡胶SBR 1502 E与SBR 1502及环保型丁苯橡胶SBR 1712 E与SBR 1712的相对分子质量及其分布、分子结构及物理机械性能基本相同;环保型丁苯橡胶的塑性比之同系列的传统橡胶要好,更有利于加工;环保型充油丁苯橡胶SBR 1723的物理机械性能要逊于SBR 1712 E和SBR 1712,但塑性较之要好.
