    摘要: The disclosure relates to a process for improving the processability, storage stability and/or cure rate of an uncured silica reinforced rubber composition where silica comprises the major filler in the reinforced rubber composition, which comprises combining a mixture comprising, rubber, silica and at least one organic compound having a low molecular weight and a functional group wherein said functional group is at least an epoxy group, such as an epoxy/ether, epoxy/hydroxyl, epoxy/ester, epoxy/amine, ether/amine, episulfide, episulfide/ether, episulfide/hydroxyl, episulfide/ester functional group located in a terminal or sterically unhindered position in the molecule of said organic compound where the molecular weight of said organic compound having a low molecular weight is less than 7,000, or the organic compound comprises an abietyl, styrenated resorcinol formaldehyde, or ester hydroxyl organic compound having a hydroxyl, ester, and optionally, an ether group, such as an ester diol.

    摘要: 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.

    摘要: 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.
