Abstract: AKD cellulosic composition obtainable by flowing a stream of a cellulosic suspension through a shearing device and in which a molten alkyl ketene dimer (AKD) is metered in to the stream of cellulosic suspension in or prior to the shearing device. The AKD cellulosic composition is particularly suitable in the manufacture of sized paper and paperboard.

Abstract: A process for preparing an aqueous styrene-butadiene polymer dispersion by free-radical aqueous emulsion polymerization of a monomer mixture M containing from 40 to 80% by weight of styrene as monomer M1, from 20 to 60% by weight of butadiene as monomer M2, and from 0 to 40% by weight, based on 100% by weight of monomers, of ethylenically unsaturated comonomers M3 other than styrene and butadiene by a monomer feed technique in the presence of from 0.05 to 0.5% by weight, based on 100% by weight of monomers, of at least one hydrocarbon HC having 6 to 20 carbon atoms, which is selected from compounds which on abstraction of a hydrogen atom form a pentadienyl radical or a 1-phenylallyl radical and from alpha-methylstyrene dimer comprises including at least 30% of the hydrocarbon HC in the initial charge to the polymerization vessel and supplying the remainder of the hydrocarbon HC to the polymerization reaction in the course of that reaction.

Abstract: The invention relates to the use of synthetic adhesives for producing corrugated cardboard at relatively low temperatures and high web speeds. The corrugated cardboard comprises a corrugated paper web and a smooth cover web, and the corrugation of the corrugated paper web is generated at paper temperatures lower than 95ºC and at a web speed greater than 150 m/min. Immediately after the corrugation of the corrugated paper web has been generated, a preferably unheated corrugation adhesive is applied in a continuous process and the corrugated paper web is glued to the at least one first cover web. The corrugation adhesive used is an aqueous adhesive dispersion on the basis of at least one synthetic, dispersed polymer having preferably a solids content of more than 40 wt %, selected from acrylate copolymers, copolymers from vinylaromatic compounds and conjugated aliphatic dienes and vinyl acetate/alkylene copolymers, wherein the glass transition temperatures of the polymers are higher than 20ºC and below the surface temperature of the corrugated paper web (preferably by at least 50ºC) to which they are applied.
