The present invention relates to rubber compositions containing a hydroxy-aryl substituted maleamic acid. The rubbers modified with the hydroxy-aryl substituted maleamic acid exhibit improved rubber/filler interaction. The hydroxy-aryl substituted maleamic acid may also be used as a replacement for resorcinol in rubber compositions and function as a methylene acceptor for reaction with conventional methylene donors.
The present invention relates to rosinate esters of N-hydroxyphenyl maleamic acid which are useful as a total or partial replacement for extender or processing oil in rubber formulations. Addition of these rosinate esters improve the modulus and tear of the vulcanizate. The rosinate esters of N-hydroxyphenyl maleamic acid are of the formula:

A method of decomposing an unsaturated carboxylic acid copolymer which comprises bonding to a molecular chain thereof a functional group having the property.of generating a free radical and then bringing a white-rot fungus or an enzyme excreted from a white-rot fungus into contact with the unsaturated carboxylic acid copolymer. The method enables an unsaturated carboxylic acid copolymer to be decomposed without adversely influencing the natural environment.
