Abstract
New additives in rubber compositions improve tire cord adhesion without need to use resorcinol. The new additives are derivatives of melamine, aceto guanamine, benzoguanamine, cyclohexylguanamine, and glycoluril, substituted with at least two vinyl-terminated radicals. Preferred compounds may also be substituted with at least one radical having a carbamylmethyl group.
Claims43
A vulcanizable rubber composition comprising uncured rubber, a vulcanizing agent and at least one additive selected from the group consisting of derivatives of melamine, acetoguanamine, benzoguanamine, cyclohexylguanamine and glycoluril monomers and oligomers of these monomers, which has been substituted on average at two or more positions on the monomer or on each unit of the oligomer with vinyl terminated radicals, the vulcanizable rubber composition being free of resorcinol.
A vulcanizable rubber composition comprising uncured rubber, a vulcanizing agent and at least one additive selected from the group consisting of derivatives of melamine, acetoguanamine, benzoguanamine, cyclohexylguanamine and glycoluril monomers and oligomers of these monomers, which has been substituted on average at two or more positions on the monomer or on each unit of the oligomer with vinyl terminated radicals, and which has been substituted on average at one or more positions with a radical which comprises a carbamylmethyl or an amidomethyl.
