A polymeric composition includes a diene elastomer; an azodicarboxy compound; and a reinforcing filler comprising silica. The composition is not foamed. A method for preparing a polymeric composition includes mixing in one or more steps: a diene elastomer; an azodicarboxy compound; and a reinforcing filler. The mixing temperature is less than 160&#xb0; C. in mixing steps in which the azodicarboxy compound is present. In an embodiment, the mixing temperature is kept below the decomposition temperature of the azodicarboxy compound.

Amino alkoxy-modified silsesquioxane adhesives for adhering steel alloy to rubber

A functionalized polyamide is prepared by reacting a thio acid with an amide monomer or a mixture of a diamine and a dicarboxylic acid. In the reaction, the amide monomer is preferably a lactam compound, the thio acid has a formula of HOOC-A-SH wherein A represents an alkylene group containing from 1 to 10 carbon atoms, the diamine is an aliphatic diamine and the dicarboxylic acid is a aliphatic dicarboxylic acid. The functionalized polyamide can be vulcanized directly with rubber, which results in the use of less dip for adhering the tire cord to the rubber.
