Abstract: Provided is a rubber composition for a sealant which can be vulcanized at low temperature and is suitable in a retentivity, an adhering property, followability and a fluidity and which is excellent in a sealing property, wherein the rubber composition is prepared by blending 100 parts by mass of a rubber component containing butyl rubber and/or EPDM, 2 to 10 parts by mass of zinc oxide, 1 to 5 parts by mass of a thiuram vulcanization accelerator, satisfying the thiuram vulcanization accelerator: the zinc oxide=1:1 to 1:3, and 150 parts by mass or more of liquid polybutene or a process oil.

Abstract: A composition includes a diene rubber and a metal phosphate ester of the formula: M being a metal with an oxidation state of +3 or +4, and R1 and R2 are independently selected from any organic moiety including hydrogen, except R1 and R2 cannot both be hydrogen. In addition, a method of making a rubber composition includes combining a solvent and a phosphate ester and mixing these to foam a solution. A source of metal ions is then added to the solution. The metal in the source of metal ions is selected from the group consisting of metals with an oxidation state of +3 or +4. The product is then is combined with a diene rubber composition to form a useful article, such as the tread of a tire.
