    摘要： A method of making a biobased-petrochemical hybrid polyol is provided. This method includes reacting a cyclic ether with a vegetable oil-based polyol in the presence of a cationic catalyst or a coordinative catalyst that includes a vegetable oil-based polyol ligand to form the biobased-petrochemical hybrid polyol. The biobased-petrochemical hybrid polyol that is created has a number average molecular weight of about 3,000 to about 6,000 and has a structure that is about 22% to about 36% biobased. In one aspect of the present invention, the cyclic ether is propylene oxide, and the propoxylated polyol formed from the propylene oxide and vegetable oil-based polyol is then reacted with ethylene oxide in the presence of a superacid catalyst to create a block copolymer with a terminal polyethylene oxide block having a high percentage of terminal primary hydroxyl groups. If the cyclic ether is a homogeneous mixture of ethylene oxide and propylene oxide, then propylene oxide-ethylene oxide random copolymers are formed by polyaddition to vegetable oil polyols. The biobased-petrochemical hybrid polyol may be reacted with an isocyanate so as to create a flexible polyurethane that has good hydrolytic resistance.

    摘要： A vegetable oil-based polyol is made by adding a peroxyacid to vegetable oil wherein said peroxyacid reacts with said vegetable oil to form epoxidized vegetable oil and adding said epoxidized vegetable oil to a mixture of an alcohol, water, and a catalytic amount of fluoboric acid so as to form a vegetable oil-based polyol. A further embodiment of the present invention involves making a vegetable oil-based polyol using an epoxidized vegetable oil as the starting material. The epoxidized vegetable oil undergoes hydroxylation by the same process as outlined above. According to another aspect of the present invention, the vegetable oil-based polyol formed by the novel methods of this invention may be reacted with an isocyanate to form a polyurethane. Alternatively, a filler such as silica may be combined with the vegetable oil-based polyol before it is reacted with the isocyanate. These polyurethanes made from vegetable oil-based polyols may be used to form electroinsulating casting resins.

    摘要： A method for making natural oil-based polyols directly from vegetable or animal oil using a consecutive two-step process involving epoxidation and hydroxylation is provided. Specifically, this process comprises adding a peroxyacid to a natural oil wherein said natural oil and said peroxyacid react to form an epoxidized natural oil and adding said epoxidized natural oil to a mixture of an alcohol, water, and a fluoboric acid catalyst. The catalytic amount of fluoboric acid is less than about 0.5% by weight of the entire reaction mixture, and the amount of water is about 10 to 30% by weight of the entire mixture. The epoxidized natural oil undergoes hydroxylation and forms a natural oil-based polyol. The present invention further includes a method for making natural oil-based polyols from epoxidized oil by hydroylating the epoxidized oil in the presence of fluoboric acid, alcohol and water in the amounts discussed above. The natural oil-based polyols created by this method may be reacted with isocyanates so as to form polyurethanes, which is another embodiment of the present invention. Alternatively, fillers such as silica may be combined with these natural oil-based polyols before they are reacted with isocyanates to form polyurethanes. In still another embodiment of the present invention, polyurethanes made from natural oil-based polyols may be used to form electroinsulating casting resins for use in electrical applications.
