  • Polyethercyclipolyols from epihalohydrins, polyhydric alcohols, and metal hydroxides or epoxy alcohols and optionally polyhydric alcohols with thermal condensation
    Patent number: 5428178
    Abstract: Method for preparing polyethercyclicpolyol by heating alkali and/or alkaline earth hydroxide optionally with polyol, its precursors or derivatives, admixing epoxy alcohol or epihalohydrin therewith to initiate an addition reaction, and thermally condensing the product of the addition reaction.
    Type: Grant
    Filed: April 7, 1994
    Date of Patent: June 27, 1995
    Assignee: Shell Oil Company
    Inventors: Anne H. Zuzich, George C. Blytas, Harry Frank
  • Polycondensation of phenolic hydroxyl-containing compounds and polyhydric alcohols and thermal condensation to form polyethercyclicpolyols
    Patent number: 5412115
    Abstract: Polyethercyclicpolyols are prepared by thermally condensing a polyol having at least three hydroxyl groups of which at least two of the hydroxyl groups are vicinal, precursors of the polyol, cyclic derivatives of the polyol, or mixtures thereof, and controlling process conditions to avoid substantial undesirable degeneration. Lower molecular weight polyethercyclicpolyols are polycondensed with phenolic hydroxyl-containing compounds to form higher molecular weight polyethercyclicpolyols.
    Type: Grant
    Filed: December 1, 1993
    Date of Patent: May 2, 1995
    Assignee: Shell Oil Company

  • Polyethercyclicpolyols from epihalohydrins, polyhydric alcohols, and metal hydroxides
    Patent number: 5371243
    Abstract: Method for preparing polyethercyclicpolyol by heating a reaction mixture of an alkali or alkaline earth metal hydroxide with a polyol, adding epihalohydrin to initiate an addition reaction, and heating the mixture until the reaction is complete.
    Type: Grant

  • Polycondensation of epoxy alcohols with polyhydric alcohols and thermal condensation to form polyethercyclicpolyols
    Patent number: 5302695
    Abstract: Polyethercyclicpolyols are prepared by thermally condensing a polyol having at least three hydroxyl groups of which at least two of the hydroxyl groups are vicinal, precursors of the glycol, cyclic derivatives of the polyol, or mixtures thereof, and controlling process conditions to avoid substantial undesirable degeneration.
