摘要： A modified conjugated diene-based polymer is provided, having remarkable processability and excellent tensile strength and viscoelasticity properties, and a rubber composition including the same is also provided. The modified conjugated diene-based polymer has a unimodal shape molecular weight distribution curve by gel permeation chromatography, narrow molecular weight distribution and a Mooney stress-relaxation ratio of 0.7 or more, and includes a functional group derived from a modifier represented by Formula 1, and thus has remarkable processability and excellent tensile properties and viscoelasticity properties.

摘要： The present disclosure relates to a modifier, and more particularly, to a modifier including a compound represented by Formula 1, and a method of preparing the same. Such modifier exhibits excellent dispersibility via hydrogen bonding with an inorganic filler when mixed therewith. The present disclosure also relates to a modified conjugated diene-based polymer and a method of preparing the modified conjugated diene-based polymer by using the modifier. The resulted modified conjugated diene-based polymer exhibits excellent processability, high tensile strength, high wear resistance, low rolling resistance, and high wet skid resistance.
