  • Patent number: 10323212
    Abstract: Polyols are produced by an alkoxylation process in which a vegetable oil containing hydroxyl functional groups is combined with a DMC catalyst to form a mixture, the DMC catalyst is then activated by adding ethylene oxide and/or propylene oxide to the vegetable oil/catalyst mixture, and ethylene oxide and propylene oxide are added to the mixture containing activated DMC catalyst in amounts such that the total of percentage of ethylene oxide in the polyol plus percentage of primary hydroxyl groups in the polyol produced is from 50 to 77% and the percentage of primary hydroxyl groups is at least 30% but less than 50%. These polyols are useful for the production of molded polyurethane foams, particularly, hot-cure molded polyurethane foams.

  • Patent number: 9035105
    Abstract: A polyether polyol based on renewable materials is obtained by the in situ production of a polyether from a hydroxyl group-containing vegetable oil, at least one alkylene oxide and a low molecular weight polyol having at least 2 hydroxyl groups. The polyol is produced by introducing the hydroxyl group-containing vegetable oil, a catalyst and an alkylene oxide to a reactor and initiating the alkoxylation reaction. After the alkoxylation reaction has begun but before the reaction has been 20% completed, the low molecular weight polyol having at least 2 hydroxyl groups is continuously introduced into the reactor. After the in situ made polyether polyol product having the desired molecular weight has been formed, the in situ made polyether polyol is removed from the reactor. These polyether polyols are particularly suitable for the production of flexible polyurethane foams.

  • Patent number: 8598248
    Abstract: 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.
