Abstract
Disclosed are copolymers of cyclic esters, e.g., caprolactone, and cyclic formals of substituted or unsubstituted diols, e.g., 1,3-dioxepane. The copolymers can provide a low melting temperature rendering them liquids at room temperature. Elastomeric polyurethanes prepared from such copolymers can exhibit a low Tg transition and good resistance to hydrolysis and oxidation. The copolymers are particularly useful for elastomers, coatings, adhesives, inks or binders requiring low temperature flexibility and good resistance to hydrolysis and oxidation.
