Liquid and Supercritical Carbon Dioxide Assisted Blending of Poly(vinly acetate) and Citric Acid

The use of liquid and supercritical carbon dioxide was explored for the blending of poly(vinyl acetate) and citric acid as a basis for developing a new process for making chewing gum which would allow for flavorings to be released slower during chewing. Mixtures of 75% of polymer and 25% citric acid...
