摘要： Economical, open-celled packaging foams of better quality than foams from commercial aromatic polyester polyols may be prepared with a novel polyol blend. The most important component in the polyol blend is an aromatic polyester polyol made from dibasic acid waste streams and recycled polyethylene terephthalate. This type of polyol made from waste or recycled reactant streams is economical to make and serves as an inexpensive substitute for a portion of more expensive amino polyols normally used.
