Abstract

Abstract Poly(dicyclopentadiene) having improved odor is obtained by incorporating in at least one of the parts of the two part metathesis polymerization catalyst system from about 2 to about 500 ppm (based on the weight of dicyclopentadiene) of liquid deodorant such as cyclacet, cyclaprop, β-damascenone, β-damascone, rose oxide, terpene C, citronellyl methyl ether, citronellyl ethyl ether, geranyl methyl ether, geranyl ethyl ether, 2,6-dimethyloctyl methyl ether, 2,6-dimethyloctyl ethyl ether, α-terpenyl methyl ether, α-terpenyl ethyl ether, methyl salicylate, methyl octin carbonate, and 1,3,5-undecatriene.
