| titleOfInvention | Epichlorohydrin/amino-polyether condensates |
| abstract | Polymers which are soluble in water or at least one organic solvent and which contain at least one tertiary and at least one quaternary basic nitrogen atom but no epoxide groups are prepared by reacting a hydroxyalkylate of ammonia, an alkanolamine or a polyalkylene polyamine having at least three hydroxy groups, with at least three equivalents of epichlorohydrin in the presence of a Friedel-Crafts catalyst, and subsequently heating the resulting a ,b -chlorohydrin. Suitable hydroxyalkylates may be prepared by reacting 6 to 350 moles alkylene oxide, preferably having 2 to 4 carbon atoms, with alkanolamines, ammonia, or polyalkylene polyamines preferably having up to 4 alkylene groups. Specified amounts of epichlorohydrin are 1.1 to 2 moles per hydroxy group. The degree of condensation during the reaction is followed by viscosity or turbity measurements. The compounds may be stored in aqueous solution after the addition of acid or reacted with ammonia, amines, mercaptan or sodium bisulphate, thiosulphate or sulphide. The Examples describe the condensation of epichlorohydrin with condensates of (1) and (4) triethanolamine and ethylene oxide, (2) diethylenetriamine and ethylene oxide, (4) ethylenediamine, propylene oxide and ethylene oxide, and (6) triethanolamine and propylene oxide.ALSO:Polymers which are soluble in water or at least one organic solvent and which contain at least one tertiary and at least one quaternary basic nitrogen atom but no epoxide groups are prepared by reacting an hydroxyalkylate of ammonia, an alkanolamine or a polyalkylene polyamine having at least three hydroxy groups, with at least three equivalents of epichlorohydrin in the presence of a Friedel-Crafts catalyst and subsequently heating the resulting a ,b - chlorohydrin.
