摘要

(CN104428321) 本​发明​描述​了​一种​制备​具有​稳定​门​尼​粘度​和​分子量​的​聚合物​的​方法。在​存在​引发​剂​的​情况下​在​烃类​溶剂​中​使​共轭​二​烯​反应​以​形成​聚合物。在​形成​所​述​聚合物​之后，将​烷​氧​基​硅​烷​末端​官能​化​基团​结合​至​所​述​聚合物。然后​任选​地​在​存在​烃​油​的​情况下，将​具有​式(R)4-nSi(OH)n​的​稳定剂​添加​至​所​述​聚合物，其中​R​为​C1​至​C18​烷基、含有​诸如​氮​或​氧​的​杂​原子​的​C1​至​C18​烷基、C4​至​C8​环烷基、或​C6​至​C18​芳​基。然后​将​所​述​聚合物​脱溶​剂，从而​产生​即使​在​长时​间内​也​具有​稳定​的​门​尼​粘度​和​分子量​的​聚合物。也​描述​了​含有​所​述​聚合物​的​组合​物​和​制品。
