Methods of preparing storage stable components useful for metathesis bulk polymerization of cycloolefin monomers are provided. These components contain cycloolefins with norbornene-functional groups and cocatalysts activated with a halometal compound. In these methods, the cocatalyst is completely formed before the halometal activator is added to prevent the formation of unwanted hydrogen halides, which catalyze undesired crosslinking reactions which destabilize the cocatalyst component. Bulk polymerization systems are provided wherein these storage stable cocatalyst components are paired with catalyst components that together form the complete metathesis catalyst system. For some embodiments, storage stability is aided by the removal of water.
