Abstract: High resiliency polyurethane foam is made from a polyether polyol having an equivalent weight of at least 1000. At least a portion of the polyether polyol is one or more random copolymer(s) formed by polymerizing a mixture of 70 to 95% by weight propylene oxide and 5 to 30% by weight ethylene oxide onto an initiator compound. The random copolymer(s) has a nominal hydroxyl functionality of at least 5, a hydroxyl equivalent weight of at least 1500 g/equivalent and no more than 0.01 milliequivalents per gram of terminal unsaturation. The randomly polymerized propylene oxide and ethylene oxide constitute at least 80% of the total weight of the random copolymer. At least 70% of the hydroxyl groups of the random copolymer are secondary hydroxyls.

Abstract: Unsaturated polyether monols are removed from polyether polyols by reaction with a functionalized thiol compound or a polythiol compound. This process replaces the terminal unsaturation with a functional group, or else couples two or more of the monols to form a polyol. The functionality of the polyether polyol product is increased by the removal of the monols.

Abstract: A method of producing a high primary hydroxyl group content and a high number average molecular weight polyol includes preparing a mixture that includes a double metal cyanide catalyst and a low molecular weight polyether polyol having a number average molecular weight of less than 1,000 g/mol, the polyether polyol is derived from propylene oxide, ethylene oxide, or butylene oxide, setting the mixture to having a first temperature, adding at least one selected from propylene oxide, ethylene oxide, and butylene oxide to the mixture at the first temperature, allowing the mixture to react to form a reacted mixture, adding a Lewis acid catalyst to the reacted mixture, setting the reaction mixture including the second catalyst to have a second temperature that is less than the first temperature, and adding additional at least one selected from propylene oxide, ethylene oxide, and butylene oxide to the reacted mixture at the second temperature such that a resultant polyol having a primary hydroxyl group content of at least 60% and a number average molecular weight greater than 2,500 g/mol is formed.

Abstract: 1,2-butylene oxide is homopolymerized or randomly copolymerized in the presence of a double metal cyanide catalyst such as a zinc hexacyanocobaltate catalyst complex. The polymers unexpectedly contain significant amounts of monofunctional impurities, which can be partially controlled through selection of polymerization conditions.

Abstract: Polymer polyols are made by polymerizing an ethylenically unsaturated monomer in a continuous polyol phase. The polymerization is stabilized with a macromer or a pre-formed polymer made by polymerizing or copolymerizing the macromer. The macromer is a random polymer of propylene oxide and ethylene oxide in defined ratios, which also contains polymerization carbon-carbon double or triple bond. Polymer polyols made in the process exhibit little viscosity rise when blended with water. Flexible polyurethane foam made from the polymer polyol exhibits excellent hardness, have good surface characteristics and, when pigmented, exhibit good, uniform coloration.

Abstract: Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.

Abstract: Random poly(propylene oxide-co-ethylene oxide) polymers are made by polymerizing a mixture of propylene oxide and a small amount of ethylene oxide in the presence of a starter and a double metal cyanide catalyst complex, and then feeding in a mixture of propylene oxide and ethylene oxide while increasing the ethylene oxide concentration in the mixture to at least 90%. This produces a polyol suitable for making high resiliency polyurethane foam without need for adding an ethylene oxide cap.
