摘要： Polyurethanes are made in a one-shot process from one or more polyols having a hydroxyl equivalent weight of at least 350, wherein at least 50% of the weight of iii) is a hydroxyl-containing polymer of propylene oxide, the hydroxyl-containing polymer of propylene oxide having a hydroxyl equivalent weight of at least 350, an average of 1.8 to 3 hydroxyl groups per molecule of which hydroxyl groups 40 to 70% are primary hydroxyl groups, an oxyethylene content of no greater than 10% by weight based on the weight of the polymer and a polydispersity of 1.175 or less. The polyurethanes exhibit excellent mechanical properties, are highly hygroscopic and cured rapidly.

摘要： A method of producing a polyether polyol that includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, the low molecular weight initiator having a number average molecular weight of less than 1,000 g/mol and a nominal hydroxyl functionality at least 2, the one or more monomers including at least one selected from propylene oxide and butylene oxide, and the polymerization catalyst being a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1. Whereas, M is boron, aluminum, indium, bismuth or erbium, R1, R2, and R3 each includes a same fluoroalkyl-substituted phenyl group, and optional R4 includes a functional group or functional polymer group. The method further includes forming a polyether polyol having a number average molecular weight of greater than the number average molecular weight of the low molecular weight initiator in the presence of the Lewis acid catalyst.

摘要： A method of producing a polyether alcohol that includes feeding an initiator into a reactor, feeding one or more monomers into the reactor, feeding a polymerization catalyst into the reactor, the polymerization catalyst being a Lewis acid catalyst having a general formula M(R1)1(R2)1(R3)1(R4)0 or 1, separate from feeding the initiator into the reactor, feeding a hydrogen bond acceptor additive into the reactor, the hydrogen bond acceptor additive being a C2 to C20 organic molecule having at least two hydroxyl groups, of which two hydroxyl groups are situated in 1,2-, 1,3-, or 1,4- positions on the organic molecule, and allowing the initiator to react with the one or more monomers in the presence of the polymerization catalyst and the hydrogen bond acceptor additive to form a polyether alcohol having a number average molecular weight greater than a number average molecular weight of the initiator.
