Abstract

Procedimiento de obtención de pasta en el que se prepara como pasta material celulósico fibroso para formar una suspensión acuosa de material celulósico, se drena la suspensión a través de un tamiz para formar una hoja de pasta y se seca la hoja de pasta para formar una pasta comercial seca, en el que se añade polímero catiónico soluble en agua a la suspensión como el único adyuvante de drenaje en el que el polímero catiónico soluble en agua es o bien, i) un copolímero que comprende (a) entre el 1 y el 70% en moles de (met)acrilamida y (b) entre el 30 y el 99% en moles de cloruro de (met)acriloiloxietiltrimetilamonio con una viscosidad intrínseca de entre 5 y 9 dl/g; o ii) un homopolímero hidrolizado de vinilformamida que comprende entre el 1 y el 100% en moles de unidades de vinilamina y que tiene un valor de K de entre 45 y 240.
