Abstract

The invention concerns an improved method for making paper which consists in using as main retention agent a branched polymer prepared in invert emulsion and bentonite as secondary retention agent (dual type system). The two additions are separated by a step for shearing the fibrous suspension (or mass). The invention enables to obtain a highly improved retention and also highly improved dewatering. Moreover, it enables to reduce the bentonite content in the white water.
