The “solid-state” ring-opening cationic polymerization of 1,3,5-trioxane: frozen polymerization for suppression of oligomer formation and synthesis of ultrahigh molecular weight polymers

Abstract

Production of polyoxymethylene with higher molecular weights and lower oligomer ratios than those obtained by molten-state polymerization of 1,3,5-trioxane was demonstrated by conducting polymerization in a “solid state”.
