  • Chewing gums and gum bases comprising block copolymers having crystallizable hard blocks
    Patent number: 9848619
    Abstract: 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.

  • GUM BASES AND CHEWING GUMS EMPLOYING BLOCK POLYMERS AND PROCESSES FOR PREPARING THEM
    Publication number: 20150230495
    Abstract: Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contain a block polymer having at least four blocks Composed of at least two different monomer systems. The block polymer exhibits an Order-Disorder Transition temperature in the range of 10 to 250° C. Chewed cuds of the chewing gum may exhibit improved removability from environmental surfaces to which they may become undesirably attached. A processing method in which the gum is mixed and/or sheeted at a temperature above the Order-Disorder Transition temperature is described.
