POLYURETHANES

Novel polyurethanes are prepared in the novel process which comprises reacting a polyisocyanate, such as toluene diisocyanate, with an oxaminated polyol. The oxaminated polyols described herein are polyols which have been reacted with a mixture of an N-substituted aziridine and a monoepoxide; such a...

Zusammenfassung:	Novel polyurethanes are prepared in the novel process which comprises reacting a polyisocyanate, such as toluene diisocyanate, with an oxaminated polyol. The oxaminated polyols described herein are polyols which have been reacted with a mixture of an N-substituted aziridine and a monoepoxide; such as polyoxypropylene glycol which has been reacted with a mixture of N-ethyl aziridine and ethylene oxide.
