<p>An organopolysiloxane, a method for preparing the organopolysiloxane, an adhesive composition containing the organopolysiloxane, and a rubber reinforcing material whose surface is treated with the adhesive composition are provided to improve heat resistance and to reduce stiffness. An organopolysiloxane comprises a repeating unit represented by the formula 1, wherein R1 is a functional group having an epoxy terminal; R2 is a functional group having an epoxy terminal, H, a hydroxyl group, a C1-C6 alkyl group, a C3-C8 cycloalkyl group, a C6-C10 aryl group or a siloxane group. Preferably the repeating unit represented by the formula 2. An adhesive composition comprises 1-10 parts by weight of the organopolysiloxane; 100 parts by weight of an aqueous solvent; and optionally a blocked isocyanate compound.</p> |
