  • Patent number: 9139506
    Abstract: Hybrid polyester-polyether polyols are prepared by polymerizing an alkylene oxide in the presence of a carboxylate initiator. The polymerization is catalyzed with a mixture of double metal cyanide catalyst complex and certain magnesium, group 3-group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal (MG3-15LA) compound makes for consistently rapid activation of the double metal cyanide catalyst complex, even in the presence of carboxylate initiator compounds. This leads to greater productivity and reduced manufacturing costs due to shorter cycle times and less waste of raw materials due to the failure of the catalyst to become activated. Once the catalyst is activated, it often polymerizes the alkylene oxide at a faster rate that the DMC catalyst by itself.

  • Publication number: 20150225504
    Abstract: Alkylene oxide polymerizations are performed in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound provides several benefits including more rapid catalyst activation, faster polymerization rates and the reduction in the amount of ultra high molecular weight polymers that are formed. The catalyst mixture is unexpectedly useful in making polyethers having low equivalent weights.

  • Patent number: 8791168
    Abstract: A viscoelastic polyurethane foam is the reaction product of at least one natural oil derived polyol and at least one aromatic compound having an average of more than one isocyanate group. A viscoelastic polyurethane foam has an air flow of at least about 0.5 l/s, wherein the foam is formed in the substantial absence of copolymer polyol and has not (yet) been mechanically reticulated and is preferably prepared using at least one natural oil derived polyol, more preferably in an amount of at least about 20 weight percent of the polyols used. A process of preparing a viscoelastic foam, comprises steps of (A) forming a reaction mixture including at least one polyol, at least one polyisocyanate, water, at least one catalyst wherein a the polyol comprises at least one natural oil derived polyol; and (B) subjecting the reaction mixture to conditions sufficient to result in the reaction mixture to expand and cure to form a viscoelastic polyurethane foam.
