Abstract: Provided are strain-hardened polymers. The polymers may include a plurality of polyether units (e.g., isotactic polypropylene oxide units) and one or more crystalline domains. The strain-hardened polymers may have a higher initial engineering yield stress and/or enthalpy of fusion than native polymer (e.g., polypropylene oxide that has not been strain-hardened). The strain-hardened polymers may be made by catalytic methods using bimetallic catalysts. Also provided are uses of the strain-hardened polymers.

Abstract: Provided are methods of producing carbonyl compounds (e.g., carbonyl containing compounds) and catalysts for producing carbonyl compounds. Also provided are methods of making polymers from carbonyl compounds and polymers formed from carbonyl compounds. A method may produce carbonyl compounds, such as, for example α,α-disubstituted carbonyl compounds (e.g., α,α-disubstituted β-lactones). The polymers may be produced from α,α-disubstituted β-lactones, which may be produced by a method described herein.
