Abstract
Process for precipitating a polycycloolefin from polymer cement comprising mixing said cement with a sufficient amount of a lower alcohol and water precipitant to cause said polymer to precipitate, and separating said polymer from the remaining liquid phase, the polymer cement having about 15 to 80% solids concentration and being a honey-like solution in a nonpolar hydrocarbon solvent of a polymer formed by ring opening polymerization of at least one monomer containing at least one norbornene group. The precipitation process can be either batch or continuous throughout.
