The present invention relates to a polymer composition comprising an anionic polymer composite having a synthesized polymer portion and a polysaccharide portion, obtainable by polymerizing vinyl monomers in the presence of the polysaccharide. The present invention further relates to a strength system and methods of production and use in providing a paper product.

Paper strength improving additives, their manufacture and use in paper making

A softener composition for use in the manufacture of paper includes a softener and an acidic material, wherein the softener composition has a relative acidity (RA) value of more than 0.05.

Softener composition

A strength additive system for manufacturing paper, board, tissue or the like includes preferably as separate components, a cationic strength agent, such as a cationic polymer with aldehyde functional groups, and an anionic copolymer obtained by polymerization of a reaction mixture including (meth)acrylamide and anionic monomers, the standard viscosity of the obtained copolymer being in a range of 1.5-5.0 mPas. A method for manufacturing of a paper, board, tissue or the like is further disclosed.

Strength additive system and method for manufacturing a web comprising cellulosic fibres

A polymer composition including an anionic synthetic polymer, an anionic polysaccharide, including a strength additive system, a paper product and a method of production.

Paper strength improving polymer composition and additive system, use thereof, and manufacture of paper products

A method for manufacturing paper is disclosed. A pulp slurry is produced, a paper sheet is formed from the slurry, an aldehyde functionalized polymer or polymers is added to the slurry before and/or after sheet formation, and a water soluble acid is added on the paper sheet.

Method for producing paper

A method for manufacturing paper is disclosed. A pulp slurry is produced, a paper sheet is formed from the slurry, an aldehyde functionalized polymer or polymers in combination with at least one additional strength additive is added to the slurry before and/or after sheet formation, and a water soluble acid is added on the paper sheet.

The present disclosure relates to a method and composition for increasing wet and/or dry strength of a paper product. The method comprises adding a composition comprising at least one polymer having a molecular weight more than 0.5 million Dalton and a degradation agent to a pulp suspension, and forming said paper product.
