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.
本发明涉及含有羟基芳基取代的马来酰胺酸的橡胶组合物。经羟基芳基取代的马来酰胺酸改性的橡胶具有更好的橡胶/填料相互作用。羟基芳基取代的马来酰胺酸还可用作橡胶组合物中
间苯二酚的替代物,并作为亚甲基受体与传统的亚甲基供体发生反应。
