Abstract

Se describe un polvo redispersable en agua a base de polímeros formadores de película insoluble, sustancialmente insolubles en agua, preparados mediante la polimerizacion de emulsion acuosa, de monomeroso etilénicamente insaturados con una estructura de nucleo/coraza que comprende un nucleo polimérico hidrofobico con una temperatura de transicion vítrea (Tg) de -30-25 degree C, de preferencia de -10-20 degree C; y una coraza unida al nucleo a través de enlaces covalentes que resulta de la reaccion del agente de injerto para injertar la coraza sobre los enlaces etilénicamente insaturados restantes en el nucleo. Tal coraza se prepara mediante la polimerizacion de emulsion sobre el nucleo de partículas, sobre una mezcla de monomero que comprende por lo menos un monomero seleccionado de estireno o un acrilato o metacrilato de alquilo de C1 C12; por lo menos un monomero que tiene un grupo sacárido y por los menos un enlace etilénicamente insaturado; y por lo menos un agente de injerto.
