Abstract
Abstract The bonding of rubber to copper and copper alloys is improved by incorporating into the rubber before vulcanisation a s-triazine carrying at the 2- position a hydroxyphenoxy, hydroxyanilino or hydroxyphenylmercapto group and optionally in each of the 4 and 6 positions a similar group or a hydroxy or chloro group or an optionally substituted amino or mercapto group. The strongest bonds are obtained by the use of 2-m-hydroxyphenoxy-4-chloro-6aminotriazines.
