Abstract

The present invention provides a method for preparing a modified and conjugated diene-based polymer, which may prevent processability degradation by restraining the increase of mooney viscosity during post-treatment using steam with high temperature or storage for a long time by stabilizing a modified polymer using a modification stabilizer, and a modified and conjugated diene-based polymer prepared by the preparation method.
