    摘要: Paper, board and cardboard are produced by draining paper stock containing interfering substances in the presence of fixing agents by a process in which the fixing agents used are reaction products which are obtainable by reacting amino- and/or ammonium-containing polymers selected from the group consisting of the polymers containing vinylamine units polyalkylene polyamines polyamidoamines ethyleneimine-grafted polyamidoamines which may be crosslinked, polydiallyldimethylammonium chlorides polymers containing dialkylaminoalkylacrylamide units or dialkylaminoalkylmethacrylamide units and polyallylamines and dicyandiamide and formaldehyde condensates with reactive sizes for paper in a weight ratio of polymer to reactive size of from 15,000:1 to 1:1, and the reaction products thus obtainable are used as fixing agents for water-soluble and for water-insoluble interfering substances in the production of paper, board and cardboard from paper stocks containing interfering substances.

    摘要: The invention relates to a process for producing polyester polyols with secondary hydroxyl end groups, including the step of the reaction of a polyester including carboxyl end groups with an epoxide of the general formula (1): wherein R1 stands for an alkyl residue or an aryl residue and the reaction is carried out in the presence of a catalyst that includes at least one nitrogen atom per molecule. The process is distinguished in that the polyester including carboxyl end groups exhibits an acid value from ≧25 mg KOH/g to ≦400 mg KOH/g and a hydroxyl value from ≦5 mg KOH/g and in that the polyester including carboxyl end groups is produced by ≧1.03 mol to ≦1.90 mol carboxyl groups or carboxyl-group equivalents of an acid component being employed per mol hydroxyl groups of an alcohol. The polyester polyols obtained, including secondary hydroxyl end groups, can be used for the purpose of producing polyurethane polymers.
