Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ELASTOMEROS DE SILOXANO QUE CONTIENEN AZUFRE. CONSISTE EN MEZCLAR UN ORGANOMERCAPTOPOLISILOXANO QUE CONSTA DE UNA COMBIANCION DE DISTINTAS UNIDADES DE SILOXANO Y TIENE MAS DE DOS UNIDADES SILOXANO QUE CONTIENEN UN RADICAL MERCAPTO POR MOLECULA Y MENOS DE 10 POR 100 EN MOLES DE DICHAS UNIDADES, CON UNA SAL ESTANNICA DE ACIDO CARBOXILICO Y UN RELLENO, Y SOMETER LA MEZCLA A REACCION DE POLIMERIZACION A LA TEMPERATURA AMBIENTE U, OPCIONALMENTE, CON CALOR, PARA FORMAR EL ELASTOMERO. ESTOS COMPUESTOS TIENEN APLICACIONES COMO CIERRES QUE CURAN RAPIDAMENTE A ELASTOMEROS, ASI COMO ADITIVOS PARA ELASTOMEROS O COMPONENTES DE MATERIALES PARA RECUBRIMIENTOS ANTICONTAMINANTES MARINOS.
