Abstract

This invention relates to an etheramine of formula (I) based on glycerine or trimethylolpropane and its manufacturing process,whereinR=H or ethyl, k=0 or 1A represents a linear or branched alkylene group having C2-C18 carbon atoms,A may be the same as or different from one another,at least one A represents a linear or branched C4-alkylene group,the sum of x, y and z lies in the range of 3 to 100,x≥y≥1 and z≥1,Z=NH2 or OH but at least two Z per molecule are NH2.
