Abstract
The present disclosure provides a non-hydrocarbyl-based alcohol initiated polyetheramine. In particular, the polyetheramine of the present disclosure is produced from a tetrahydrofurfuryl alcohol-based initiator which is alkoxylated and then reductively aminated. The polyetheramine of the present disclosure may be used in a variety of applications, such as a raw material in the synthesis of a dispersant for use in an aqueous pigment dispersion.
