The present invention relates to a new process for improving dewatering when manufacturing a film comprising high amounts of microfibrillated cellulose (MFC) without negatively impacting the film properties. According to the present invention a high amount of nanoparticles is used as an additive, optionally together with a polymer.

A process for making down a powder is provided. The process comprises making down a powder comprising one or more acrylamide-based polymer(s) to form a made down powder solution, comprising blending a mixture of the powder and a solvent for no more than about 15 minutes to yield the made down powder solution, wherein the powder comprises particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns.

A filtered smoking article includes an aerosol generation rod, a filter disposed at a downstream end of the aerosol generation rod, and tipping paper wrapped around a downstream end part of the aerosol generation rod and an outer circumferential surface of the filter and connecting the aerosol generation rod and the filter. The tipping paper is paper containing bleached pulp and unbleached pulp, and fibers of the unbleached pulp have a length of 1 mm to 4 mm and a thickness of 20 μm to 70 μm.

The present invention relates to a polymer complex obtained by inverse emulsion polymerization of water-soluble monomers: in the presence of a cationic water-soluble host polymer comprising amine functions.

The present invention concerns a composition being an inverse emulsion comprising cross-linked anionic, organic polymeric microparticles, said microparticles having an unswollen z-average particle size diameter of less than 0.75 μm, wherein the organic polymeric microparticles are formed from a monomer mixture comprising (a) an ethylenically unsaturated carboxylic acid, or a salt thereof; (b) an ethylenically unsaturated non-ionic monomer; and (c) from 1 to 10 mole % of 2-acrylamido-2-methylpropanesulphonic acid, or a salt thereof. The invention also provides a process for preparing the composition, the use of the composition in a paper or paperboard making process and methods of making paper or paperboard employing said composition.

A method of incorporating a low molecular weight polymer (e.g., polymer strength aid) into an industrial process (e.g., papermaking process) is provided. The method comprises treating an industrial process (e.g., paper sheet precursor) with a powder or wetted powder, wherein the powder comprises a polymer dry polymer (e.g., polymer strength aid), wherein the polymer dry polymer (e.g., polymer strength aid) has a weight average molecular weight of from about 10 kDa to about 2,000 kDa.

This method for treating the surface of paper and/or one of the layers thereof, comprises the following successive steps: i) Supplying an aqueous suspension S of polysaccharide; ii) Supplying an aqueous dispersion D comprising (a) particles of at least one anionic water-swellable polymer P and (b) at least one compound selected from a mineral salt, an organic salt, an organic dispersing polymer and the mixtures thereof; iii) Mixing the suspension S and the dispersion D to obtain a mixture M; iv) Applying the mixture M to the surface of the paper and/or to at least one of the layers thereof.

The invention relates to a method for producing paper, board or the like. The method comprises obtaining a fibre stock comprising lignocellulosic fibres and adding a retention agent system comprising a cationic synthetic polymer to the fibre stock and forming a fibrous web from the fibre stock and drying the web.
