THE NEW POLYMER SYSTEM FOR IMPROVING FINE AND PAPER RETENTION AND DRAINAGE ON PULP AND PAPER MACHINE This invention relates to a completely new polymer system for this application, that can be used with an enhancer, to improve fine and fiber retention and drainage on pulp and paper machine. The fine and fiber retention can be achieved for kraft, sulphite (high and low yield), bisulphite, mechanical, OPCO, BTCMP, TCMP, BCMP, hard wood, such as oak, birch, maple, elm, wild-cherry, and TMP pulps and any mix in any proportion of two or more types of pulp.
