Structure-property relationships-linear and star-branched macrostructures

摘要

The continuously-prepared SSBR samples were also fully characterized.SSBR-A is a linear material,while SSBR-B is a silicon tetrachloride coupled product.Table 7 provides a comparison between the polymerization processes,micro-structure and macrostructure of the two materials.The mi-crostructures are somewhat different;however,the Tgs of the two materials are identical.
