the invention relates to degradable chewing gum polymer , said degradable polymer is a polymer polymerized from at least one trifunctional or higher functional initiator , at least two different monomers forming the backbone of the polymer and at least one monomer selected from the group of carbonate monomers . according to the invention it has been realized that a certain degree of branching of the backbone is needed to obtain a final improved performance , when the polymer , preferably the elastomer , is incorporated in a chewing gum . it has moreover been realized that the obtained degree of branching needs and may actually be carefully controlled in order to avoid too much branching - induced crosslinking .
