Abstract

PROCEDIMIENTO PARA SUPRIMIR ACUMULACIONES EN LAS SUPERFICIES INTERNAS DE REACTORES DE POLIMERIZACION DE CLORURO DE VINILO EN SUSPENSION ACUOSA. CONSISTE EN DEPOSITAR DE FORMA ADHERENTE, SOBRE LAS SUPERFICIES INTERNAS DEL REACTOR Y ANTES DE INICIARSE LA POLIMERIZACION, UN REVESTIMIENTO CONSTITUIDO POR UN PRODUCTO OBTENIDO A PARTIR DE LA CONDENSACION DE FORMALDEHIDO Y UN L-NAFTOL DE FORMULA (I), EN LA QUE N VALE 0 O 1; M VALE 0-3; Y R Y R PUEDEN SER VARIOS TIPOS DE RADICALES. LA REACCION DE CONDENSACION SE CATALIZA POR ACIDOS O BASES.
