Patent ID: 8591967

Claim:
Chewing gum comprising: at least one biodegradable polymer having a molecular weight within the range of 105000 g/mol (Mn) to 350000 g/mol (Mn); and at least one softener in an amount of less than 12% by weight of the chewing gum; wherein the chewing gum is free of non-biodegradable polymers; wherein the at least one biodegradable polymer obtained by the polymerization of one or more cyclic esters by ring-opening and where at least one of the cyclic esters are selected from the groups consisting of glycolides, lactides, lactones, cyclic carbonates and mixtures thereof; wherein lactone monomers are chosen from the group consisting of ∈-caprolactone, δ-valerolactone, γ-butyrolactone, β-propiolactone and mixtures thereof; and wherein the lactone monomers are optionally substituted with one or more alkyl or aryl substituents at any non-carbonyl carbon atoms along the ring, including compounds in which two substituents are contained on the same carbon atom.
