BISTRI(HYDROXYPOLYALKYLENEOXY) SILYLALKYLPOLYSULFIDE, METHOD OF MANUFACTURING BISTRI(HYDROXYPOLYALKYLENEOXY)SILYLALKYL POLYSULFIDE, TIRE RUBBER ADDITIVE, AND TIRE RUBBER COMPOSITION

摘要

A bis[tri(hydroxypolyalkyleneoxy)silylalkyl] polysulfide, i.e., a polysulfide that contains bonded hydroxy-polyalkyleneoxy groups instead of alkoxy groups in the bis(trialkoxysilylalkyl) polysulfide; a method of manufacturing of the aforementioned polysulfide by heating a bis(trialkoxysilylalkyl) polysulfide and a polyalkyleneglycol; a tire rubber additive to a tire rubber composition that comprises a bis[tri(hydroxypolyalkyleneoxy)silylalkyl] polysulfide alone or a mixture of bis[tr (hydroxypolyalkyleneoxy)silylalkyl] polysulfide and a polyalkyleneglycol; and a tire rubber composition that contains the aforementioned additive.
