Abstract
A method includes contacting one or more beta-propiolactone monomers and one or more phosphorous compound in a solution under conditions such that a polypropiolactone polymer is formed. The solution comprises one or more polar protic solvents and the one or more phosphorous compounds. The phosphorous compound comprises phosphorous in an ionic form that is either covalently bound to another compound to form a zwitterion or ionically bound to another compound to form a salt.
Claims39
A method, comprising:
- a) contacting one or more beta-propiolactone monomers and one or more phosphorous compounds and optionally one or more carboxylate compounds in a solution under conditions such that a polypropiolactone polymer is formed,
- wherein the solution comprises one or more polar protic solvents and the one or more phosphorous compounds and optionally the one or more carboxylate compounds, and
- wherein the phosphorous compound comprises phosphorous in an ionic form that is either covalently bound to another compound to form a zwitterion or ionically bound to another compound to form a salt.
