Abstract
Disclosed are methods of efficiently making poly(3-hydroxypropionate) and related copolymers from beta propiolactone utilizing carboxylate salts of an onium cation. In another aspect, the present invention provides polymerization systems comprising combinations of initiators and monomers that together enable the efficient production of poly(3-hydroxypropionate) and related copolymers. Disclosed are novel polymer compositions having structures and/or compositional characteristics that differentiate them from previously produced polymers and polymer compositions.
