  "abstract": "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.",
  "claims": [
    "1. An adhesive for a polyolefin rubber moulding, said adhesive comprising: (a) 100 parts by weight of an unvulcanized rubber; (b) 0.01 to 10 parts by weight of a halogenated isocyanuric acid, said halogenated isocyanuric acid containing in a molecule thereof of a group: ##STR4## wherein X is halogen atom; and (c) an organic solvent to dissolve or disperse said unvulcanized rubber.",
    "2. The adhesive as claimed in claim 1, wherein said polyolefin rubber moulding is an automobile weatherstrip.",
    "3. An adhesive for a polyolefin rubber moulding, said adhesive comprising: (a) 100 parts by weight of an unvulcanized rubber; (b) 0.01 to 10 parts by weight of a halogenated isocyanuric acid, said halogenated isocyanuric acid containing in a molecule thereof a group: ##STR5## wherein X is halogen atom; (c) a vulcanizing agent; (d) a vulcanization accelerator; and (e) an organic solvent to dissolve or disperse said rubber.",
    "4. The adhesive as claimed in claim 3, wherein said polyolefin rubber moulding is an automobile weatherstrip."

  "description_excerpt": "This is a continuation of application Ser. No. 826,013, filed Feb. 4, 1986, which was abandoned upon the filing hereof.\n\n1. Field of the Invention\n\nThe present invention relates to rubber compositions having strong adhesive force to various rubbers including vulcanized polyolefin rubbers and, adhesives as well as primers comprising the rubber compositions.\n\n2. Description of the Related Art\n\nAs rubbers for industrial use, various synthetic rubbers such as polyolefin rubber, styrene-butadiene copolymer rubber (SBR), polybutadiene rubber (BR), isobutylene-isoprene copolymer rubber (IIR), polychloroprene rubber (CR), acrylonitrile-butadiene copolymer rubber (NBR), polyisoprene rubber (IR), etc. or natural rubber (NR) are employed.\n\nAmong them, vulcanized polyolefin rubbers represented by ethylene-propylene-diene terpolymer rubber (EPDM) and ethylene-propylene copolymer rubber (EPM) possess many superior properties that are excellent in weather resistance, aging resistance and resistance to ozon, provide a wide temperature range for use from -50° to 150° C., and the like. Therefore, vulcanized polyolefin rubbers have now been used in many fileds of industry, including rubber parts for automobiles such as weatherstrips, glass run, moldings, etc.\n\nOn the other hand, it is known that the aforesaid vulcanized polyolefin rubbers such as EPDM, EPM, etc. contain no polar group in the main chain of the molecule thereof so that even though paints or adhesives are applied to the surface thereof, the resulting coating are liable to be stripped off.",
