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, .beta.-damascenone, .beta.-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, .alpha.-terpenyl methyl ether, .alpha.-terpenyl ethyl ether, methyl salicylate, methyl octin carbonate, and 1,3,5-undecatriene.
Claims20
In a two-part metathesis polymer catalyst system wherein part one comprises a catalyst activator and optionally a rate moderator, and part two comprises WCl.sub.6 and WOCl.sub.4 and optionally a phenolic compound and/or a chelating agent and/or t-butanol, and wherein at least one of said catalyst parts contains dicyclopentadiene monomer, the improvement comprising at least one of said catalyst parts containing from about 2 to about 500 ppm (based on the weight of dicyclopendadiene) of liquid deodorant selected from the group consisting of cyclacet, cyclaprop, .beta.-damascenone, .beta.-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, .alpha.-terpenyl methyl ether, .alpha.-terpenyl ethyl ether, methyl salicylate, methyl octin carbonate, and 1,3,5-undecatriene.
