    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: Elastomers are prepared from a reaction mixture that contains a polyene compound, an epoxy resin, a thiol curing agent and a basic catalyst. The polyene compound has an average of at least two groups containing aliphatic carbon-carbon double bonds capable of reaction with a thiol group. At least one of said aliphatic carbon-carbon double bonds is separated from each other said aliphatic carbon-carbon double bond by an aliphatic spacer group having a weight of at least 500 atomic mass units. These elastomers are typically phase-separated materials having good elongation and tensile properties.

    Abstract: A curable composition includes a reaction product of an isocyanate component that includes one or more isocyanates, at an isocyanate index being from 90 to 150, and an isocyanate reactive component that includes a blend including from 5 wt % to 95 wt % of a first butylene oxide based polyol and from 5 wt % to 95 wt % of a second butylene oxide based polyol. The first butylene oxide based polyol has a number average molecular weight from 200 g/mol to 1,000 g/mol and a nominal hydroxyl functionality from 2 to 6. The second butylene oxide based polyol has a number average molecular weight greater than 1,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from 2 to 4. The blend accounts for at least 50 wt % of a total weight of polyols in the isocyanate-reactive component.
