摘要
集成橡胶ＳＩＢＲ是一种新型橡胶，应用于轮胎胎面，可同时减小摩擦阻力、改善抗湿滑性。其结构特点是分子链由多种链段结构构成，因而有多个玻璃化转变温度，其ｔａｎδ曲线呈现宽峰。采用多步加料法、连续聚合法、条件渐变法、偶联法等聚合工艺，可合成多种链段结构的分子链。
? Integral rubber SIBR,which can be utilized in making tires,has an excellent combination of properties of rolling resistance and wet-gripping.The typical feature of such copolymer is a specially arranged multi-block or sequence structure.This kind of copolymer can be prepared by various anionic polymerization processes,such as multi-stage process,continous process,etc.
