1 / 1 Summary u00e2u20acu0153espessante, formulau00e3u2021u00e3u0192o u00e3ufffdcida, uses a formulau00e3u2021u00e3u0192o u00e3ufffdcida, a formulau00e3u2021u00e3u0192o alkaline, and a thickener, and formulau00e3u2021u00e3u0192o alcalinau00e2u20acufffd this invenu00e3u00a7u00e3u00a3o refers to a thickener which can be obtained according to a mu00e3todo,Characterized in that a polu00e3u00admero t obtained by a polimerizau00e3u00a7u00e3u00a3o in emulsu00e3u00a3o inverse of (a) at least one monu00e3u00b4mero etilenicamente unsaturated solu00e3u00bavel in u00e3gua comprising at least one monu00e3u00b4mero aniu00e3u00b4nico and / or at least one monu00e3u00b4mero nu00e3u00a3o iu00e3u00b4nico, (b) at least one monu00e3 u00b4mero associative etilenicamente unsaturated, (c) optionally at least one reticulador,(d) optionally at least one agent of transferu00e3u00aancia chain. The temperature is kept constant during the polimerizau00e3u00a7u00e3u00a3o in emulsu00e3u00a3o inverse and becomes at least 40 C, preferably between 50 to 90 C, and the activator is added apu00e3u00b3s the polimerizau00e3u00a7u00e3u00a3o in emulsu00e3u00a3o inverse to obtain the thickener.
