The present invention relates to a method for preparing a modified conjugated diene-based polymer having excellent compounding properties and improved processability. According to the method, a first polymer including a functional group is prepared using a modifier represented by Formula 1, and the first polymer is mixed with a sulfur halide. A modified conjugated diene-based polymer having excellent affinity with a filler, excellent compounding properties such as tensile properties and viscoelasticity properties, and excellent compounding processability, may be prepared.
本发明涉及一种制备改性共轭二烯基聚合物的方法,该聚合物具有优异的共混性能和更佳的加工性能。根据该方法,使用式 1 所代表的改性剂制备包含官能团的第一种聚合物,并将第一种聚合物与卤化
硫混合。这样就可以制备出一种改性共轭二烯基聚合物,该聚合物与填料的亲和性极佳,具有优异的共混性能(如拉伸性能和粘弹性能)和优良的共混加工性能。
