POLYETHER POLYOLS HAVING REDUCED UNSATURATION AND POLYURETHANE FOAMS PREPARED THEREFROM

摘要

Polyether polyols prepared by oxyalkylating a 1,2-diaminocycloalkane have reduced levels of unsaturation andmay be used to prepare melamine containing flame retardantpolyurethane foams capable of passing California 117 and133, and other flame tests.
