Abstract: front page image
(EN)A process is disclosed for the production of paper and paper-like products from a suspension of papermaking materials to which poly(ethylene oxide) and a phenolic type cofactor which may be produced by a Williamson synthesis from a resin, are added to improve the retention of fibres, of fines, of dispersed extractives and of fillers during the processes of water removal for the manufacturing of paper.
