ABSTRACT:
A unitary pack of smoking tobacco products is provided in which a flavorant is incorporated in some of the smoking tobacco products in the form of a polymeric alcohol flavorant-release composition which has the general formula: ##STR1## wherein R is selected from aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; R.sup.1 and R.sup.2 are selected from hydrogen and aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; and n is an integer. These polymers release a flavorant when heated. Such polymers include polymers formed from .alpha.-substituted vinyl menthyl carbonate esters, such as poly(.alpha.-methylvinyl .alpha.-menthyl carbonate) and poly(.alpha.-styryl .alpha.-menthyl carbonate), which release menthol when heated. Smoking tobacco products which are made with tobacco which has been treated with a particular alcohol flavorant-release composition have been found to show no significant loss in delivery of flavor. Other smoking tobacco products which are packaged therewith do not acquire the flavor of the flavorant which is contained in the alcohol flavorant-release composition, despite the absence of internal vapor barriers between the different flavored tobacco products.
