Polymeric etheramines, their production and use

Polymeric etheramines (P) obtainable by reaction of (A) an oligohydroxycompound which is an oligohydroxyalkane of molecular weight >= 92 and with x hydroxygroups, wherein x is a number in the range of 3 to 6, or a mixture of two or more thereof, or a mixture of one or more thereof with at least one alkanediol containing 2 to 4 carbon atoms, with (B) epichlorohydrin, in the ratio of more than two moles of (B) per mole of (A) and on average not more than 1.2 molecules of (B) per hydroxygroup of (A), to give a chloro-terminated adduct (E), and exhaustive reaction of (E) with (C) at least one aliphatic oligoamine containing at least one primary amino group and at least one further amino group which is primary or secondary, in the molar ratio of n moles of (C) for every mole of (E), wherein n > 1 and smaller than the number of linked chlorine atoms in (E) present on average per molecule of (E), and optionally (D) at least one aliphatic mono- or diamine containing only one primary or secondary amino group any further amino group being tertiary, in the molar ratio of p moles of (D) for every mole of (E), wherein p is sufficient for reacting any available chlorine of (E) not reacted with (C), and in such a ratio of [(C) + (D)] to (E) that the total number t of basic amino groups in [(C) + (D)] is higher than the total number of linked chlorine atoms in (E), and which are optionally protonated, and aqueous compositions thereof, their production and their use as multifunctional adjuvants in the processing of cellulosic fibres in aqueous medium, especially as flocculants, drainage or retention assistants, dye fixatives and trash quenchers in paper and tissue production.
