Papermaking furnish comprising solventless cationic polymer retention aid combined with phenolic resin and polyethylene oxide

摘要

Disclosed is a papermaking furnish comprising a combination of a flocculating solventless cationic polymer retention aid with phenolic resin and polyethylene oxide as a retention system for retaining fines, fillers and other papermaking chemicals in the paper sheet characterised in that the flocculating solventless cationic polymer retention aid is a liquid, aqueous solventless dispersion of a cationic polymer without any oil-phase, having viscosities in waster at 1% of between 2000 and 20,000 mPa sec. Further disclosed is a method of increasing retention rate and/or drainage in a papermaking furnish comprising adding to he furnish an effective amount of a liquid, aqueous solventless cationic polymer flocculating retention aid having viscosities in water at 1% of between 2000 and 20,000 mPa sec in combination with phenolic resin and polyethylene oxide.
