Continuous bulk polymerization of 2-pyrrolidone

摘要

A process for forming polymers of 2-pyrrolidone in pellet form via bulk polymerization is disclosed. Polymerization accelerators are empolyed to markedly shorten the polymerization time thus making possible a compact continuous polymerization apparatus which produces pellets of high polymer content requiring no further polymerization. The pellets are formed by forcing the polymerizing mixture through small tubes to form rods of polymer which are then cut into short lengths.
