ABSTRACT:
A method for the polymerization of a monomer is disclosed. The method includes (a) providing a reaction mixture comprising a monomer, a stabilizer precursor, and a polymerization initiator in a polymerization medium comprising carbon dioxide; and then (b) polymerizing the monomer and the stabilizer precursor in the polymerization medium to form a heterogeneous reaction mixture comprising a polymer in the polymerization medium. The stabilizer precursor is covalently bound the polymer to provide an intrinsic surfactant in the polymer, which stabilizes the polymer in the heterogeneous reaction mixture.
