Flavoring method and composition which include a carboxylate having the general formula: ##STR1## where R.sub.1 is an alkyl having from 1 to 14 carbons, alkenyl having from 2 to 14 carbons, cycloalkyl, cycloalkenyl, aryl, or furyl having from 4 to 14 carbons; R.sub.2 is alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, or cycloalkynyl of from 1 to 7 carbons, aryl or oxyaryl of from 5 to 18 carbons, or a cycloaliphatic ether of from 5 to 6 carbons; and R.sub.3 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, or cycloalkynyl of from 1 to 7 carbons, aryl, or oxyaryl of from 5 to 18 carbons, or a cycloaliphatic ether of from 5 to 6 carbons, or a radical of the general formula: ##STR2## where R.sub.4 and R.sub.5 independently are hydrogen or alkyl of from 1 to 6 carbons; and R.sub.6 is aryl, alkylaryl, aryloxy, alkoxy, cyclic acetal of from 3 to 7 carbons, dioxyalkyenyl ether of from 4 to 8 carbons; and M is cation other than hydrogen ion.

Flavoring method and composition

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.

Polydicyclopentadiene having improved odor

Carboxylates having the general formula: ##STR1## and a method of flavoring foodstuff and tobacco compositions therewith wherein R.sub.1 is an alkyl having from 1 to 14 carbons, alkenyl having from 2 to 14 carbons, cycloalkyl, cycloalkenyl, aryl, or furyl having from 4 to 14 carbons; R.sub.2 is alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, or cycloalkynyl of from 1 to 7 carbons, aryl or oxyaryl of from 5 to 18 carbons, or a cycloaliphatic ether of from 5 to 6 carbons; and R.sub.3 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, or cycloalkynyl of from 1 to 7 carbons, aryl, or oxyaryl of from 5 to 18 carbons, or a cycloaliphatic ether of from 5 to 6 carbons, or a radical of the general formula: ##STR2## where R.sub.4 and R.sub.5 independently are hydrogen or alkyl of from 1 to 6 carbons; and R.sub.6 is aryl, alkylaryl, aryloxy, alkoxy, cyclic acetal of from 3 to 7 carbons, dioxyalkyenyl ether of from 4 to 8 carbons; and M is cation other than hydrogen ion.
