Abstract

1. Procedimiento para la obtención de dispersiones acuosas de polímeros, caracterizado porque se polimerizan en emulsión como mínimo un monomero polimerizable, clefínicamente insaturado, en presencia de un iniciador de la polimerización hidrosoluble constituido por una (N, N''-hidroxialquil).amidina de ácido azo-di-isobutírico de la fórmula general (I) **(Fórmula)** donde R1 y R2 son iguales o diferentes y significan restos alquilo lineales o ramificados con 2 hasta 4 átomos de carbono y X significa hidrógeno o R''-OH.
