摘要： 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.

摘要： Disclosed herein are polymers, copolymers and polymer systems based on polypropiolactones which can be biodegradable and can enhance the recyclability of polymer systems, which can be functionalized to introduce desired functionality into the polymers and/or which may optionally be prepared from renewable raw materials. Disclosed are novel functionalized beta propiolactones. Some of the novel functionalized beta propiolactones have functional groups bound to the ring structure of the lactone that provide improved polymer systems. Disclosed are novel homopolymers of the functionalized beta propiolactones. Disclosed are novel copolymers based on the functionalized beta propiolactones with beta propiolactone or other monomers which copolymerize with the functionalized beta propiolactones.

摘要： Disclosed are methods of efficiently making poly(3-hydroxypropionate) (polypropiolactones) and related copolymers from 3-hydroxypropionate (beta propiolactone) utilizing zwitterionic polymerization initiators. 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) (polypropiolactones) and related copolymers. Disclosed are novel polymer compositions having structures and/or compositional characteristics that differentiate them from previously produced polymers and polymer compositions.
