Abstract
Se describen procesos para elaborar elastómeros vulcanizados, al menos parcialmente, y composiciones termoplásticas procesables que constan de dichoselastómeros, y elastómeros, composiciones y artículos de caucho que se obtienen a través dedich os procesos. Estos elastómeros se obtienen al reticular almenos parcialmente un polímero elastómerico que contiene sustituyentes activos con un agente de reticulación que posee un peso molecular promedio inferiora 2000, que contienen dos o mássusti tuyentes reactivos que difieren de los contenidos en el polímero elastomérico, cada uno de los sustituyentes seselecciona del grupo que consta de ácido carboxílico, anhídrido carboxílico, sal de ácido carboxílico, haluro carbonilo,hidroxi, ep oxi e isocianato demodo tal que los del elastómero reaccionarán con los del agente de reticulación para reticular el elastómero al menos parcialmente. Se prepara unelastómero reticulado al menos parcialmente mediante unproceso que consi ste en hacer reaccionar al poner en contacto (i) un polímero elastomérico quecontiene sustituyentes reactivos y (ii) un agente de reticulación (a) que contiene dos o más sustituyentes reactivos que difieren de loscontenidos enel polímero el astomérico y (b) que posee un peso molecular promedio inferior a alrededor de 2000, cada uno de los sustituyentes reactivos se seleccionan demodo que el elastómero reaccionará con los del agente de reticulación parareticular al menos parcial mente el elastómero y cada uno de los sustituyentesreactivos se selecciona de un grupo que consta de ácido carboxílico, anhídrido carboxílico, sal de ácido carboxílico, haluro carbonilo, hidroxi,epoxi eisocianato. Otro aspecto es el elast ómero reticulado, al menos parcialmente, que se obtiene mediante el proceso antes mencionado.
