Abstract: Processes are disclosed for reducing the viscosity of compositions containing one or more polymeric compounds so as to make them transportable by adding a subcritical compressed fluid, which fluid is a gas at standard conditions of 0 C and one atmosphere pressure.

Abstract: A process which comprises (i) the generation of release surfaces by application to predetermined areas of a solid surface of a solution, suspension or dispersion of a release agent and a supercritical fluid that vaporizes from the release agent, (ii) the deposition of a mass onto the release surface containing the release agent, and (iii) the separation of the mass or a product derived from the mass from such surface covered by the release agent. Novel apparatus for carrying out the process are described.
