Verfahren zur Herstellung von stickstoffhaltigen Polykondensationsprodukten

The invention comprises nitrogen containing condensation products formed from N-b -hydroxyalkyl derivatives of ammonia, of mono-or polyamines which contain at least two active H atoms attached to N atoms, of primary carboxylic acid amides, or primary sulphonic acid amides, or from mixtures thereof with primary mono- or polyamines, monofunctional secondary amines, amines containing at least two secondary amino groups, primary carboxylic acid amides, primary sulphonic acid amides, monohydric alcohols or phenols, polyhydric alcohols or polyethers or polyesters of M.W. 200-5000, which alcohols, polyethers or polyesters are free from S and N, by condensation reactions at 120 DEG to 300 DEG C. in the presence of phosphoric acid, polyphosphoric acid, p-toluene sulphonic acid, boron phosphate, HF-aluminium oxide, fuller's earth, Friedel-Crafts catalysts, Friedel-Crafts addition compounds, phophorous acid or derivatives thereof, or phosphonous acid or derivatives thereof.ALSO:The invention comprises nitrogen containing condensation products formed from N-b -hydroxyalkyl derivatives of ammonia, of mono- or polyamines which contain at least 2 active H atoms linked to nitrogen, of primary carboxylic acid amides, of primary sulphonic acid amides or from mixtures thereof with primary mono- or polyamines, monofunctional secondary amines, amines containing at least two secondary amino groups, primary carboxylic or sulphonic acid amides, polyhydric alcohols or polyethers or polyesters which have a M.W. of 200-5000, which alcohols, polyethers and polyesters are free from S and N, by condensation reactions carried out in the presence of phosphoric acid, polyphosphoric acid, sulphuric acid, p-toluene sulphonic acid, boron phosphate, fuller's earth, hydrofluoric acid-aluminium oxide, Friedel-Crafts type catalysts or addition compounds, phosphorous acid or derivatives thereof or phosphorous acid or derivatives thereof at 120 DEG to 300 DEG C.
