Abstract

Una dispersión acuosa de partículas poliméricas, comprendiendo las partículas (a) un polímero de núcleo preparado a partir de al menos un monómero hidrofílico etilénicamente insaturado; (b) al menos un primer polímero de cubierta que encapsula al menos parcialmente el polímero de núcleo, estando preparado el primer polímero de cubierta a partir de una mezcla de reactivos que comprende (b)(i) al menos un monómero hidrofílico etilénicamente insaturado y (b)(ii) al menos un monómero aromático que tiene un grupo hidrofílico surfactante y un grupo etilénicamente insaturado que reacciona con el monómero hidrofílico etilénicamente insaturado (b)(i); (c) al menos un segundo polímero de cubierta que encapsula parcialmente al menos el primer polímero de cubierta, estando el segundo polímero de cubierta preparado a partir de una mezcla de reactivos que comprende (c)(i) al menos un monómero aromático que tiene un grupo etilénicamente insaturado y (c)(ii) un monómero aromático que tiene un grupo hidrofílico surfactante y un grupo etilénicamente insaturado que reacciona con el monómero aromático (c)(i); y (d) un tercer polímero de cubierta opcional que encapsula al menos parcialmente el segundo polímero de cubierta, estando el tercer polímero de cubierta preparado a partir de al menos un monómero aromático polimerizable, en donde la partícula polimérica define un vacío.
