Abstract

um método para estabilizar uma borracha natural tal como guaiúle. o método inclui a etapa de introduzir pelo menos um de uma amina e um anti-oxidante fenólico, tal como mada, a uma forma de látex da borracha sob condições tal que o anti-oxidante torna-se quimicamente ligado à borracha. o método inclui a etapa adicional de subsequentemente tratar a borracha para remover pelo menos uma porção substancial de resinas arrastadas. o método pode produzir uma composição de borracha de, por exemplo, borracha de guaiúle e incluindo um anti-oxidante quimicamente ligado a este. a borracha resultante pode ser adequada para o uso na construção de pneus.
