Abstract
método para produzir uma folha de papel ou de papelão a partir de uma suspensão fibrosa. a presente invenção se refere a um método para fabricar uma folha de papel ou de papelão a partir de uma suspensão fibrosa, compreendendo as seguintes etapas: a) injetar um polímero p2 em uma suspensão fibrosa, b) formar uma folha de papel ou de papelão, c) secar a folha de papel ou de papelão, o polímero p2 sendo preparado, antes da etapa a), a partir de um polímero solúvel em água p1 na forma de partículas sólidas, sendo p1 constituído por pelo menos um monômero não iônico escolhido dentre acrilamida, metacrilamida, n,n-dimetilacrilamida e acrilonitrila, o polímero p1 sendo submetido a uma reação re para formar um polímero p2, a reação re incluindo a adição e dissolução das partículas sólidas do polímero p1 em uma solução aquosa m1 de: (i) um hidróxido alcalino e/ ou um hidróxido alcalino-terroso, (ii) um hipo-haleto alcalino e/ou um hipo-haleto alcalino-terroso, antes de um tempo de reação de 10 segundos a 5 horas.
