Organic polysiloxane, adhesive composition comprising the same, and rubber stiffener treated thereby
Patent number: 8202931Abstract: The present invention relates to a novel polymer, an adhesive composition including the same, and a rubber reinforcing material treated with the same, and more particularly to an organic polysiloxane including a certain repeating unit, an adhesive composition including the same, and a rubber reinforcing material treated with the same. Because the organic polysiloxane and the adhesive composition including the same is superior in reactivity to a hydroxyl group, an amide group, or an amine group, and has high thermal resistance and low stiffness, the composition is preferably used for surface-treating a rubber reinforcing material such as a tire cord and make it possible to provide a rubber reinforcing material such as a tire cord having good properties.Type: GrantFiled: March 6, 2008Date of Patent: June 19, 2012Assignee: Kolon Industries, Inc.Inventors: Jae-Woong Lee, Young-Se Oh, Gi-Woong Kim -
