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.

摘要： A process is described for the preparation of mixed isomeric methylene-bridged polycyclohexylpolyamines wherein a mixed isomeric methylene-bridged polyphenyl polyamine mixture having a functionality of from about 2.0 to about 3.3 is pretreated by contacting the mixture and hydrogen with a nickel-containing hydrogenation catalyst at a temperature of from about 25.degree.C. to about 250.degree.C. under a pressure of about 500 to about 15,000 psig. The pretreated isomeric polyamine is then hydrogenated in the presence of ammonia under conventional hydrogenation conditions employing a ruthenium-containing hydrogenation catalyst. The pretreatment step allows the utilization of mixed isomeric methylene-bridged polyphenyl polyamine feed mixtures for the production of isomeric methylene-bridged polycyclohexylpolyamines in high yields without attendant deactivation of the ruthenium hydrogenation catalyst heretofore observed. The process is particularly applicable to continuous operation.
