ABSTRACT:
The present invention provides a method for making primary amine terminated linear polyethers of molecular weight above about 3500 which have virtually no contamination from in-chain secondary amine functionalities or amine-terminated tertiary amine side-chains. This method involves the production of novel intermediates.
The invention also provides purely linear polyether-polyurea block copolymers formed by chain extension of the primary amine terminated linear polyethers.
