Abstract
"ESPESSANTES DE LáTEX SOLúVEIS EM áLCALIS" São revelados espessantes solúveis em álcalis, os quais compreendem um produto de reação de (A) um monómero de ácido carboxílico insaturado, (B) um monómero monoetilenicamente insaturado diferente do monómero (A), e (C) um macromonómero alcoxilado, hidrofóbico polimerizável com os monómeros (A) e (B). O monómero monoetilenicamente insaturado diferente do monómero (A) contém um grupo metila, preferivelmente é um acrilato e mais preferivelmente é o acrilato de metila. Os polímeros revelados se solubilizam a um pH de a partir de cerca de 4, 5 até 6, 0, com isto produzindo polímeros particularmente úteis para uso em composições cosméticas.
