Abstract
The copolymerizations of N‐vinyl‐2‐pyrrolidone/styrene and N‐vinyl‐2‐pyrrolidone/methyl methacrylate—both systems with extremely different reactivity ratios—have been investigated in a recording dilatometer equipped with a thermo‐couple. The shrinkages of the systems can be described by the theory of Wittmer. The necessary values for the homopolymerizations as well as the binary reactivity ratios have been determined. The shrinkages have been verified independently by density measurements.Keywords
