Abstract
An in-situ method for performing organic metathesis polymer chemistry in the solid state includes the step of providing an organic monomer and a catalyst, the catalyst for driving a metathesis polymerization reaction of the monomer. The organic monomer can be provided as a liquid monomer. The reaction produces reaction products including a polymeric end product and at least one volatile reaction product. At least a portion of the volatile reaction product is removed during the reaction to favor formation of the reaction product. Significantly, the reaction is performed at a temperature being below an average melting point of the polymeric end product such that at least a portion of the reaction is performed in the solid phase.
