ABSTRACT:
The preparation of isocyanurate foams from a recycled polyethylene terephthalate polyol modified with aromatic amino polyols, sucrose polyols, ethoxylated alphamethyl glucosides, alkoxylated glycerine or alkoxylated sorbitol is disclosed. These modified foams exhibit improved fluorocarbon solubility. The foams may be used for building roofing and sheathing applications.
