CA 2440080

There is provided a novel degradable gum base comprising low molecular weight elastomer replacement compounds which are generally applicable for chewing gum formulations. In particular there is provided a gum base and a chewing gum comprising a polyester polymer obtainable by the polymerisation of two or more different cyclic ester monomers, wherein the cyclic ester monomers have a low glass transition temperature (Tg) and the polyester polymer has a glass transition temperature (Tg) in the range from (-20 ~C) to (-80 ~C).

La présente invention concerne une base de gomme dégradable comprenant des composés de substitution d'élastomère à faible poids moléculaire qui peuvent généralement être appliqués pour des formulations de gomme à mâcher. L'invention concerne en particulier une base de gomme et une gomme à mâcher comprenant un polymère de polyester pouvant être obtenu par la polymérisation d'au moins deux monomères d'esters cycliques différents, les monomères d'esters cycliques possédant une température de transition vitreuse (Tg) faible et le polymère de polyester possède une température de transition vitreuse (Tg) comprise entre -20·C et -80 ·C.
