ABSTRACT:
A bulk or mass polymerization process is provided which involves bulk polymerization of vinyl monomers in a liquid phase in the presence of a nitrogen rich vapor phase containing amounts of nitric oxide effective to inhibit formation of popcorn polymer in the vapor head space during the reaction. The process may be used as a step in the formation of polymer or may be used as the entire reaction process.
