    Abstract: 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.

    Abstract: A cured composition including a reaction product of a mixture that includes an isocyanate component having one or more isocyanates and an isocyanate-reactive component having a butylene oxide based polyol, which has a number average molecular weight greater than 2,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from (2) to (4). At least (50) wt % of a total weight of alkylene oxides used to form the butylene oxide based polyol is butylene oxide. An isocyanate index of the mixture is from (90) to (150). The cured composition in a cured state exhibits a first tan delta peak between a first temperature range of 50° C. to 0° C. and a second tan delta peak between a second temperature range of 75° C. and 150° C., according to a tan delta plot over a range of temperatures, and a value of the first tan delta peak and a value of the second tan delta peak each represents a ratio of a loss modulus of the cured composition and a storage modulus of the cured composition at a specific temperature within the range of temperatures, as measured according to dynamic mechanical thermal analysis. The values of the first and the second tan delta peaks are from (0.10) to (0.90).

    Abstract: A flooring coating composition includes a coating agent that is a reaction product of an epoxy based formulation, the epoxy based formulation being at least one of an epoxy prepolymer formulation, an epoxy-silane hybrid formulation, and an epoxy thiol acrylate formulation. The coating agent in a cured state exhibits a first tan delta peak between a first temperature range of 75 C to 0 C and a second tan delta peak between a second temperature range of 20 C and 75 C, according to a tan delta plot over a range of temperatures. A value of the first tan delta peak and a value of the second tan delta peak each represents a ratio of a loss modulus of the coating agent and a storage modulus of the coating agent at a specific temperature within the range of temperatures, as measured according to dynamic mechanical thermal analysis. The values of the first and the second tan delta peaks are from 0.10 to 0.80.
