31,567 IMPROYED RIGID POLYURETHANES AND POLYISOCYANURATE FORMS ABSTRACT OF THE DISCLOSURE Novel rigid polyurethane and/or polyisocyanurate foams are disclosed which have fine cell structure, low K-factor, and flame retardance. These foams are prepared by the reaction of a polyisocyanate with herterocyclic nitrogen containing polybeta-hydroxy urethane functional polyols which act as chemically bound flame retardants. Also disclosed are novel modified poly-beta-hydroxyalkyl carbamylalkylated heterocyclic nitrogen containing polyols useful for the formation of rigid foams.
