选择了三种丁苯橡胶(SBR)——乳聚丁苯胶(ESBR)、溶聚丁苯C(SSBR(C))及溶聚丁苯B(SSBR(B))，用红外光谱(FTIR)分析了它们的链化学结构.同时，用动态力学谱(DMA)和示差扫描量热谱(DSC)研究了这三种SBR与天然橡胶(NR)的混容性.结果表明，SSBR(B)与NR具有很好的混容性.三种SBR与NR混容性的差别，与SBR链化学结构不同有关.

Three typical styrene-butadiene rubbers(SBR)were chosen:emulsion-SBR(ESBR)and two kinds of solution-SBR(SSBR(C)) and (SSBR(B)). Fourier transform infrared(FTIR) was used to analysis the chain structure; dynamic mechanical analysis (DMA) and differential scanning calorimeter (DSC) were used to study the compatibility of these three SBR with NR. The results show that:the blend system of SSBR(B) with NR is compatible. The blend systems of ESBR and SSBR(C) with NR exhibit two-phase morphology. The differences in compatibility among the three kinds of SBR with NR can be well explained by comparing their chain structure. The content of cis-1,4 polybutadiene (PB) in SSBR(B) is more than that in the other two SBRs and the content of 1,2-add PB is the lowest.
