ABSTRACT:
A high flash point cycloolefin composition, including at least 50% by weight dicyclopentadiene, the composition having a flash point of greater than 100.degree. F. and a viscosity of from about 3 cps to about 3000 cps at about 70.degree. F. and about 1 atmosphere pressure. The cycloolefin composition is used in a method of preparation of cycloolefin for polymerization by metathesis catalysis to form a substantially crosslinked thermoset polymer by: distilling the cycloolefin to form distilled cycloolefin, and contacting the distilled cycloolefin and an adsorbent.
