ABSTRACT:
The preparation of isocyanurate foams from a recycled polyethylene terephthalate polyol modified with alkoxylated amines and alkoxylated amides is disclosed. These modified foams exhibit improved fluorocarbon solubility, and do not cause the resultant polyols to be monofunctional, but rather difunctional. The foams may be used for building, roofing and sheathing applications.
