Abstract
Implementations described herein relate to an etheramine mixture containing a cyclobutane based amine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the ehteramine mixture. The etheramine mixture may be used in a variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.
