    Abstract: A method of producing a polyether polyol includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, and the low molecular weight initiator has a nominal hydroxyl functionality of at least 2. The one or more monomers includes at least one selected from propylene oxide and butylene oxide. The polymerization catalyst is 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, R3, and R4 are each independent, R1 includes a fluoroalkyl-substituted phenyl group, R2 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, R3 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3.

    Abstract: A curable composition includes (A) a first component having from 5.0 wt % to 39.0 wt %, based on the total weight of the first component, of a toughening agent component including a Bisphenol F based epoxy resin and an urethane acrylate component, a hardener component having at least one amine based hardener and is present in a ratio of 0.8 to 1.2, based on a number of equivalents of amino hydrogen groups in the hardener component to a number of equivalents of reactive groups in the first component capable of forming a covalent link with the amine reactive groups in the hardener, and an epoxy base component that accounts for a remainder of the total weight of the first component and that has at least one epoxy resin separately provided from the Bisphenol F based epoxy resin. The Bisphenol F based epoxy resin is present in an amount from 2.5 wt % to 50.0 wt % and the urethane acrylate component is present in an amount from 50.0 wt % to 97.5 wt %, based on the total weight of the toughening agent component. The urethane acrylate component includes the capping reaction product of an acrylate and an isocyanate terminated prepolymer and the isocyanate-terminated prepolymer is the reaction product of a polyisocyanate and at least a DMC derived polyol having a molecular weight of at least 3000 g/mol. The curable composition may further include (B) an optional second component that has at least one of a filler and any additional ingredient for a targeted application of the curable composition.
