Abstract: The invention relates to a method for producing paper, paperboard and cardboard in the presence of an aqueous suspension of components containing fine-particles of filler material. The fine-particle filler materials are covered at least partially with water-soluble amphoteric copolymers. Said method consists in adding to the fibre suspension, prior to the formation of the sheet, and in addition to the aqueous suspension of components containing fine-particles filler material, at least one cationic and/or amphoteric polymer which, as a structural element, does not contain any ester unsaturated carboxylic acids with quaternised amino alcohols.

Abstract: The inventive method for producing paper, paperboard and cardboard by removing interfering substance-containing water from a paper pulp in the presence of polymers containing vinylamine units whose mean molecular mass Mw is equal or greater than one million. Said method consists in preparing, at first a high-density pulp, introducing a doses quantity at least of one type polymer which contains vinylamine units and whose mean molecular mass Mw is equal or greater than one million and a degree of hydrolysis ranges from 1 to 20 mol % in the high-density pulp, in diluting said high-density pulp by adding water until a low-density pulp is obtained and in dewatering said low-density pulp. Said invention also relates to the use of homo-or copolymers of N-vinyl carboxylic acid amides having a degree of hydrolysis ranging from 1 to 20 mol % and a mean molecular mass Mw equal or greater than one million for producing paper, paperboard and cardboard in the form of an additive to the high-density pulp containing interfering substances in order to reduce deposits formed in the sieving, pressing and drying areas of paper machines.
