PROCESS FOR PRODUCING MODIFIED CONJUGATED DIENE-BASED POLYMER, MODIFIED CONJUGATED DIENE-BASED POLYMER, AND POLYMER COMPOSITIONAn object of the present invention is to provide a process for producing a modified conjugated diene based polymer suitable for preparing a polymer composition excellent in the fuel cost saving effect. The presentinvention provides a process for producing a modified conjugated diene-based polymer, comprising reacting a conjugated diene-based. polymer having a monomer unit based. on a conjugated diene compound and a monomer unit based on a compound represented by the following formula (1), with an organemetallic compound, and reacting the resulting reaction15 product with a hydrocarhyloxysilane compound: wherein I:34 and It=:=1 each represent a hydrogen atom or an ath,:,group, at least one Rn and Et t5 ni an all. Rh', R=7 andeach represent a h 'pm or a 1wdrc:arhylgronp„ represents a Mderm group, ana. K represent U or I. |
