Ring-Opening Metathesis Polymerization is now possible without any solvent. A mechanochemical tool, ball-milling, provides sufficient mixing and energy delivery to the mixture of solid catalyst and monomers. A group of norbornene monomers of various functional groups including ionomer was polymerized quickly by the simple ball-milling. Details of reaction parameters such as the liquid-assisted grinding selective prohibition of chain degradation will be disclosed.
