ABSTRACT:
A polymer modified with an alkoxysilane is prepared by a reaction forming a bond between an alkoxysilane compound represented by General Formula (I) and at least one of end parts of a conjugated diene/vinylaromatic hydrocarbon copolymer obtained by copolymerization of a conjugated diene and a vinylaromatic hydrocarbon using a lithium compound as an initiator. An adhesive composition contains 3% by weight or more of the polymer modified with an alkoxysilane. The polymer is used for an adhesive composition, can be prepared by a simple process, has excellent adhesive property and durability so that an additive such as a tackifier is not always required, and has essentially enhanced adhesive property to inorganic materials, in particular. The adhesive composition in which the polymer is used has excellent adhesive property and durability. ##STR1##
