Etheramines containing flexible and rigid segments and their use as intermediates for polymer synthesis

摘要

The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkyloxating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.

主权项

1. An etheramine mixture comprising at least 10% by weight, based on the total weight of the etheramine mixture, of a monoether diamine of formula (I): wherein R is a radical of a cycloaliphatic or hydrogenated aromatic diol after removal of the two hydroxyl groups and X and Y are identical or different and are each, independently of one another, hydrogen, a linear or branched C1-C5 alkyl group, a linear or branched C2-C5 alkenyl group, or a substituted or unsubstituted C6-C12 aryl group.
