Embodiment Construction

[0017] A strategy for the development of gum base elastomers has been to develop polymers with low glass transition temperatures that are either completely amorphous or slightly crystalline with a crystalline melting point below room temperature.

[0018] A preferred route to prepare such polymers is to use a combination of two or more low Tg monomers such that these different repeat units hinder crystallization.

[0019] Accordingly, one aspect of the present invention relates to polyester polymers comprising polymers obtained by the polymerization of two or more different cyclic ester monomers, wherein the cyclic ester monomers have a low glass transition temperature (Tg), and the polyester polymers have The glass transition temperature (Tg) is in the range of (-20°C)-(-80°C).

[0020] Preferably, the cyclic ester monomer is selected from 4-membered lactone, 5-membered lactone, 6-membered lactone, 7-membered lactone, 8-membered lactone, 5-membered ring carbonate, and 6-membe...

Abstract

The invention provides a novel degradable gum base comprising low molecular weight elastomer replacement compounds which are generally applicable for chewing gum formulations. In particular the invention provides 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 DEG C) to (-80 DEG C).

Description

technical field [0001] The present invention relates to the field of chewing gum. In particular, there is provided a novel degradable gum base containing low molecular weight elastomer replacement compounds commonly used in chewing gum formulations. Specifically, the present invention provides a gum base and chewing gum comprising polyester polymers obtained by polymerizing two or more different cyclic ester monomers, wherein the cyclic ester monomers have a low glass transition temperature (Tg ), and the glass transition temperature (Tg) of the polyester polymer is in the range of (-20°C)-(-80°C). Background technique [0002] It is generally believed that chewing gum that is spit out in indoor and outdoor environments causes considerable nuisance and inconvenience because it sticks firmly to surfaces such as streets and sidewalks and stays where it exists. Or action people's shoes and clothes. A major cause of these troubles and inconveniences is the fact that currently...
