Estimating the term…
Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contains a block copolymer having at least two hard crystallizable polymeric blocks and at least one soft polymeric block. At least one hard polymeric block is a hard crystallizable polymeric block has a melting point greater than 20° C. The hard, crystallizable polymeric blocks and the soft blocks each have a degree of polymerization of at least 15 Characteristics of the block copolymers can be selected to produce gum bases and chewing gums having desired properties. In some cases, chewed cuds formed from the gum bases may exhibit improved removability from environmental surfaces to which they may become undesirably attached.
A chewing gum comprising a sweetener, a flavoring agent and a chewing gum base comprising a block copolymer comprising at least one soft polymeric block and at least two hard, crystallizable polymeric blocks, wherein the hard, crystallizable polymeric blocks have a melting point greater than 20° C. and wherein the polymeric blocks each have a degree of polymerization of at least 15 and wherein the at least one soft block comprises a random copolymer of 1-octene and ethylene and wherein the at least two hard blocks comprise a polymer that is essentially an ethylene homopolymer.
