  • Molded and slab polyurethane foam prepared from double metal cyanide complex-catalyzed polyoxyalkylene polyols and polyols suitable for the preparation thereof
    Patent number: 6066683
    Abstract: Copolymer DMC-catalyzed polyoxypropylene polyols which exhibit processing latitude similar to base-catalyzed copolymer analogs and base-catalyzed homopolyoxypropylene analogs may be prepared by oxyalkylation with a mixture of propylene oxide and ethylene oxide such that a finite ethylene oxide content is maintained in the oxyalkylation reactor for the most substantial part of the oxyalkylation, the polyoxypropylene polyol having randomly distributed oxyethylene moieties which constitute 1.5 weight percent or more of the polyol product.
    Type: Grant
    Filed: April 3, 1998
    Date of Patent: May 23, 2000
    Assignee: Lyondell Chemical Worldwide, Inc.
    Inventors: Robert W. Beisner, Chiu Yan Chan, Thomas P. Farrell, Danny J. Frich, Mark R. Kinkelaar, Jack R. Reese, II, Donald F. Rohr, Wolfgang Schmidt, Andrew M. Thompson
  • Molded and slab polyurethane foam prepared from double metal cyanide complex-catalyzed polyoxyalkylene polyols and polyols suitable for the preparation thereof
    Patent number: 6008263
    Abstract: Copolymer DMC-catalyzed polyoxypropylene polyols which exhibit processing latitude similar to base-catalyzed copolymer analogs and homopolyoxypropylene analogs may be prepared by oxyalkylation with a mixture of propylene oxide and ethylene oxide such that a finite ethylene oxide content is maintained in the oxyalkylation reactor for the most substantial part of the oxyalkylation, the polyoxypropylene polyol having randomly distributed oxyethylene moieties which constitute 1.5 weight percent or more of the polyol product. Block copolymer polyols having external blocks containing lesser oxyethylene content than internal blocks and bicompositional compositions containing discrete multimodal and dissimilar and optionally multimodal polyols produced by a continuous addition of starter process are useful as polyols exhibiting greater processing latitude.
