Abstract

Se ha descubierto que los aceleradores de N, N-dialquilditilocarbamilo cíclico para la vulcanización con azufre de caucho, generalmente funcionan tan bien como los aceleradores de N, N-dialquilditiocarbamilo de cadena recta correspondientes, pero de manera sorprendente, no producen cantidades detectables de N-nitrosaminas medio-ambientales indeseables. Los aceleradores de N, N-alquilditiocarbamilo ramificados están representados generalmente por la fórmula (I); donde R es un grupo alquilo que puede o no estar ramificado, o un grupo alquilo cíclico o un grupo alcarilo o arilo, X es otro grupo tiocarbamilo de la misma estructura general, un grupo alquilamina primario, un grupo alquiltio, un grupo 2-benzotiazilo, o un ion de metal, y n es un entero de 1 a 6. Los aceleradores de ditocarbamilo de la presente invención están representados por la fórmula (II); donde X es otro grupo tiocarbamilo de la misma estructura general, un grupo alquilamino primario, un grupo alquiltio, un grupo 2-benzotiazilo, o un ion de metal, y n es un entero de 1 a 6.
