Patent number: 4771093Abstract: The rubber composition of the present invention comprises rubbers and halogen compounds. As the rubbers, vulcanized or unvulcanized rubbers are employed. The vulcanized rubber compositions are obtained by applying unvulcanized rubbers together with the halogen compounds, vulcanizing agents and vulcanization accelerators to subjects to be coated and then heating them. These rubber compositions all exhibit a strong adhesive force to various rubbers and therefore, they are useful as adhesives or subbing agents for various rubbers including vulcanized polyolefin rubbers.Type: GrantFiled: April 10, 1987Date of Patent: September 13, 1988Assignee: Toyoda Gosei Co., Ltd.Inventors: Masakazu Nakane, Tatsuya Murachi
