ABSTRACT:
A method and apparatus for the modification of the physical properties of polymers through pressure processing techniques. The apparatus is comprised of a piston device which acts on the polymer substrate charged within the confines of a compression chamber. The piston delivers an abrupt pressure change to the substrate for the purpose of effecting the desired modification of physical properties including altered thermal, viscosity, solubility, turbidity and hardness profiles. Predictable characteristics may be imparted to the substrate through variation of pressure duration and intensity as well as the number of piston strokes applied. Modification of the physical properties of starch and gum arabic, in particular, is disclosed.
