Abstract

"PROCESSO PARA REDUZIR A QUANTIDADE DE MONÈMERO RESIDUAL EM DISPERSõES AQUOSAS DE POLìMEROS POR PóS-TRATAMENTO COM UM SISTEMA INICIADOR" A invenção refere-se a um processo para reduzir efetivamente a quantidade de monómeros residuais em uma dispersão aquosa de polímeros por tratamento secundário da dispersão opcionalmente sob pressão com um sistema iniciador que compreende a) um hidroperóxido, peróxido de hidrogênio ou um perácido e b) um ácido <244>-hidroxicarboxílico como o ácido tartárico ou um sal derivado do mesmo.
