Abstract:
1. A method of making an amino acid-containing polymer, the method comprising the steps of: (a) providing a monomer comprising a diene functionalized with an amino acid or amino alcohol; (b) forming a reaction mixture by contacting the monomer with an agent capable of catalyzing the polymerization of the monomer into a polymer wherein said agent is a ruthenium based catalyst or osmium metal carbene complex catalyst comprising metal centers that are in the +2 oxidation state and are of the general Formula I; wherein M is ruthenium or osmium; n is an integer between 0–5; L and L R, R X and X Z and Z wherein any two or more of X, X (c) placing the reaction mixture under conditions that result in the formation of the polymer in the reaction mixture; wherein the monomer has a structure: wherein y is an integer greater or equal to 1, n is an integer greater than 1, m is an integer greater than 2, R is a moiety comprising a hydrogen atom and a carbon atom, and R
