This invention is directed to treating the surfaces of rubber-reinforcing materials with a gas plasma of O.sub.2 and CF.sub.4 to activate the surfaces to make them more receptive to adhesives. Optionally the surfaces of the reinforcing materials may be exposed to a polymerizing gas plasma such as a thio-carbon to coat the surfaces of the reinforcing material with substances that promote adhesion to rubber. The treated surfaces have been shown to adhere directly to rubber when vulcanized in the normal fashion.

Process for the surface treatment of polymers for

A cured rubber tire having a surface coated with at least one of polyvinylpyrrolidone and a monavalent water soluble salt of methylvinylether/maleic acid copolymer.

Tire with cured rubber portion containing titanium dioxide over which is

A cured rubber tire having a surface coated with at least one of polyvinylpyrrolidone and a monovalent water soluble salt of methylvinylether/maleic acid copolymer.

Tire with coating thereon to inhibit staining

There is disclosed a method for enhancing the cure of a sulfur vulcanizable elastomer which comprises adding to the vulcanizable elastomer a mixture of tall oil fatty acids comprising at least (a) from about 28% to about 55% by weight of oleic acid, (b) from about 25% to about 40% by weight of linoleic acid, (c) from about 4% to about 20% conjugated linoleic acid and (d) from about 0% to about 8% rosin acids. Use of a mixture of tall oil acids as a cure activator significantly lowers the cost of producing the vulcanizate while concomitantly improving the adhesion and dynamic properties of the elastomer.

Tall oil fatty acid mixture in rubber

Tire coating composition (non-wax) composed of a rubber selected from polybutadiene and/or styrene/butadiene copolymer, carbon black having a large particle size and, preferably, a non-ionic surfactant and use thereof for curing tires. Optionally, the composition can also contain at least one of mica and talc.

Tire coating composition and use for curing tires

Good adhesion of rubber to metal is very important in rubber articles containing metal reinforcement. For example, in a steel belted tire good adhesion between the tire rubber and the metal tire cord is of utmost importance. Good metal to rubber adhesion is also of great importance in a variety of other rubber products, including power transmission belts, conveyor belts, and rubber hoses containing metal reinforcements. This invention reveals the use of certain adhesion promoters that are useful in rubber products containing metal reinforcements. More specifically, this invention discloses the use of allyl phosphite esters, allyl phosphate esters, 5-nitro isatoic anhydride, iminodiacetic acids, N-substituted iminodiacetic acids, salts of N-substituted iminodiacetic acids, and salts of iminodiacetic acids as adhesion promoters in composites containing rubber and metal.

Rubber-metal adhesion promoters

A lubricant composed of a siloxane, a fatty acid lubricant, mica and at least one selected thickener and use thereof for curing tires.

Lubricant and use thereof for curing tires

There is disclosed a method for adhering rubber to reinforcing materials which comprises embedding a textile fiber or metal reinforcing material in a vulcanizable rubber composition comprising rubber, a vulcanizing agent, reinforcement, a methylene donor, and a phenolic ester as a methylene acceptor.

Enhanced adhesion of rubber to reinforcing materials through the use of

Composite of rubber and metal reinforcement where the rubber contains borate and a cross-linkable monomer. Cured composite is useful as component for rubber tires, industrial belts and hose.

Composite of rubber and metal reinforcement therefor

Composite of rubber and metal reinforcement where the rubber contains a cyanuric acid derivative and optionally a borate. Cured composite is useful as component for rubber tires, industrial belts and hose.

An amide particularly suitable as a light stabilizer and also for copolymerizing with other monomers, wherein said amide has the following structure: ##STR1## where R.sub.1 is an aryl radical having the structure: ##STR2## WHERE A AND A' ARE SELECTED FROM HYDROGEN, HYDROXYL AND MEDIUM ALKYL HYDROCARBON RADICALS; B AND B' ARE SELECTED FROM HYDROGEN AND MEDIUM TO LOWER ALKYL HYDROCARBON RADICALS, AND C IS SELECTED FROM MEDIUM TO LOWER ALKYL HYDROCARBON RADICALS, ARYL KETONE RADICALS, 2'-HYDROXY ARYL KETONE RADICALS AND 4'-OCTYL ARYL KETONE RADICALS; R.sub.4 is selected from the aryl radicals of R.sub.1 and from aliphatic hydrocarbon radicals having from 1 to 8 carbon atoms; R.sub.2 is selected from hydrogen, methyl, ethyl, phenyl and --CH.sub.2 X radicals, where X is selected from chlorine, bromine or fluorine radicals; R.sub.3 is selected from medium and lower alkyl, cycloalkyl and aryl radicals; and where R.sub.5 is selected from hydrogen, methyl and chlorine radicals.
