Investigations on vinylene carbonate, 2. Copolymerization with N ‐vinyl‐2‐pyrrolidone and ethyl vinyl ether

Functional monomers and polymers have received considerable attention in recent years, especially in the biomedical field. In this respect, poly(viny1ene carbonate) is very interesting, because the reactive carbonate groups offer the possibility of coupling with bioactive compounds containing amino groups, e. g. proteins or enzymes. Copolymerization of vinylene carbonate with other vinyl monomers will affect the amount of carbonate groups as well as other properties of the copolymers. In a previous paper we described the preparation and properties of poly(viny1ene carbonate) I), and this paper reports the copolymerization of vinylene carbonate with N-vinyl-2-pyrrolidone and with ethyl vinyl ether.
