摘　　要：用丁苯橡胶(SBR)与乙烯焦油在430℃、常压及惰性气体保护下进行共炭化,制备出各向异性中间相沥青,并对其进行了分析和表征。结果表明,由SBR改性乙烯焦油制得的中间相沥青与乙烯焦油直接炭化制得的中间相沥青相比,有序度高,黏度低,β树脂含量高,且具流线广域性组织结构。Anisotropic mesophase pitches （ SBR- ET-MPP） were prepared by ethylene tar（ET） cocarbonized with butadiene-styrene rubber（SBR） at 430℃ , and under atmospheric pressure and in N2 atmosphere. SBR-ET-MPP was analyzed and characterized. The results showed that there was higher order degree, and lower viscosity, and much more β resin content, and linear texture for SBR-ET-MPP as compared with mesophase pitch direct carbonized from ethylene tar.
