Unsaturated carbonic acid derivatives III. Copolymerization behavior of S‐, O‐ and N‐vinyl derivatives of carbonic acid

S‐Vinyl‐N‐diethyl monothiolcarbamate, O‐Vinyl‐N‐diethyl carbamate, and N‐Vinyl‐N‐methyl‐S‐ethyl monothiocarbamate were copolymerized with styrene and vinyl acetate. The ALFREY‐PRICE Q‐ and e‐values were calculated and compared with those of other S, O, and N‐vinyl monomers. The S‐vinyl thiolcarbamate was found to be more reactive as a comonomer than the N‐ or O‐vinyl compounds.
