Abstract

This invention relates to polyetheramines based on 1,3-dialcohols, in particular to an etheramine mixture comprising at least 90% by weight, based on the total weight of the etheramine mixture, of anamine of Formula (I) and/or (II), wherein R1-R12 are independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, wherein at least one of R1-R6 and at least one of R7-R12 is different from H, wherein A1-A9 are independently selected from linear or branched alkylenes having 2 to 18 carbon atoms, preferably 2-10 carbon atoms, most preferably 2-5 carbon atoms, wherein Z1-Z4 are independently selected from OH or NH2, wherein at least one of Z1-Z2 and at least one of Z3-Z4 is NH2, and wherein the sum of x+y is in the range of from 2 to 200, wherein x≥1 and y≥1; and x1+y1 is in the range of from 2 to 200, preferably 2-20, most preferably 2-10, wherein x1≥1 and y1≥1.
