Abstract
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.
