    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: An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds.
