Abstract: The invention relates to a continuous process for the preparation of amphiphilic graft polymers, wherein a vinyl ester component(B) composed of vinyl acetate and/or vinyl propionate (B1) and, if desired, a further ethylenically unsaturated monomer (B2), is polymerized in the presence of a polyalkylene oxide (A), a free radical-forming initiator (C) and, if desired, an additive(D), at a mean polymerization temperature at which the initiator (C) has a decomposition half-time of from 1to 500 min, in at least one tubular reactor segment with a feed side and an outlet side, through which the reaction mixture comprising at least a part of component (A) to (C), and if desired (D), streams. The invention further relates to an inventive amphiphilic graft polymer and the use thereof.

Abstract: La invención se refiere a un método para producir soluciones acuosas de homo- o copolímeros de ácido acrílico por medio de polimerización radical de ácido acrílico y comonómeros monoetileno insaturados solubles en agua en un medio acuoso en la presencia de por lo menos un iniciador soluble en agua y por lo menos un regulador soluble en agua, en donde la polimerización se realiza por medio de un proceso continuo, y en donde los componentes de bajo peso molecular son por lo menos parcialmente separados de la solución polimérica acuosa obtenida después de la polimerización. Los mezcladores microestructurados y los reactores se utilizan de preferencia para la polimerización. Por lo menos un reactor y/o mezclador que tiene microestructuras se utiliza de preferencia para el proceso.
