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 an alcohol ethoxylate surfactant or lubricant includes reacting a low molecular weight initiator with ethylene oxide in the presence of a polymerization catalyst, the low molecular weight initiator having a nominal hydroxyl functionality at least 1, 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. R1, R2, and R3 are the same fluoroalkyl-substituted phenyl group. The method further includes forming the alcohol ethoxylate surfactant or lubricant 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.
