An objective of the present invention is to provide a hydrogenated modified polymer which can afford a molded body excellent in improvement in the balance among the impact resistance, the strength, the adherability and as the appearance, and a process for producing the same as well as a composition containing the same. Another objective is to provide a composition which can afford a molded body excellent in the balance among the flame retardancy, the tensile strength, the tensile extension, the heat resistance, the characteristic at low temperature, the insulation property, the pliability and the like. The hydrogenated modified polymer of the invention is a hydrogenated polymer of a modified conjugated diene-based polymer obtained by reacting an alkoxysilane compound to a polymer which is polymerized a conjugated diene or a conjugated diene and another monomer using an organic alkali metal compound as a polymerization initiator in an inert organic solvent such as cyclohexane and the like. The hydrogenated modified polymer composition of the invention contains the above-mentioned hydrogenated modified polymer and at least one selected from the group consisting of nonpolar polymer, polar polymer and filler.
