    摘要： A process for purifying polyether polyols prepared using double metal cyanide (DMC) catalysts is disclosed. The process involves combining a mixture of the polyol and a C.sub.1 -C.sub.6 aliphatic alcohol with an amount of a chelating agent effective to form an insoluble complex with the catalyst, then filtering the polyol mixture to remove the insoluble complex. The process, which requires that the polyol and alcohol be present in a relative weight ratio of from 1:1 to 100:1, is effective for removing DMC residues and any cations introduced with the chelating agent.

    摘要： The present invention provides a process for producing a rigid polyisocyanurate foam involving reacting at an isocyanate index of from about 175 to about 400, a polyisocyanate with at least one natural-oil polyol containing at least about 35 wt. %, based on the weight of the polyol, of natural oil, having a hydroxyl number from about 175 to about 375 and a hydroxyl functionality of about 2.0 to about 2.8, in the presence of a blowing agent and optionally, in the presence of one or more of surfactants, flame retardants, pigments, catalysts and fillers, wherein the resulting foam has a renewable biobased content of at least 8% by weight. The foams provided by the inventive process possess properties similar to foams produced from petroleum-derived materials and may find use in wall or roof insulation systems. The high biobased content (>8%) may allow wall or roof insulation systems containing these foams to be considered for the U.S. Government's preferred procurement program.

    摘要： The present invention provides flexible conventional polyurethane foams made from at least one polyisocyanate and at least one vegetable oil alkoxylated in the presence of a double metal cyanide (DMC) catalyst, optionally at least one non-vegetable oil-based polyol, generally in the presence of a blowing agent and optionally in the presence of a surfactant, pigment, flame retardant, catalyst or filler. The alkoxylated natural oil must have (a) an ethylene oxide content in the alkoxylated segment greater than 20% by weight, (b) a primary hydroxyl group content of at least 10%, with the sum of (a)+(b) being at least 30% but no greater than 60%, The alkoxylated natural oils are environmentally-friendly, bio-based polyols which can be used to increase the “green” content of polyurethane foams without having detrimental effects on foam properties.
