Abstract

A process for forming a foamed structure, which comprises ejecting from a closed container a liquid propellant composition comprising a synthetic film-forming polymer in an amount within the range of from about 10 to about 60% by weight of the composition in solution in a liquid propellant boiling at a temperature below 7.22º c, at atmospheric pressure, and retained in the composition in the liquid phase at a pressure above atmospheric, the propellant being in a sufficient amount within the range of about 20 to about 70% by weight of the composition to form, by rapid volatilization of the propellant at atmospheric pressure and temperature, a foamed, voluminous, coherent structure containing open and/or closed cells; and dispersed or dissolved in the composition an additive in an amount within the range of about 5 to about 700% by weight of the polymer, in excess of the amount soluble in the polymer in the absence of the propellant, and which is deposited in the cells or walls of the structure when the propellant is volatilized, and which can be separated from the cells of the structure, with any organic liquid present, which is a solvent for the polymer and boils at, or above, 7.22ºC at atmospheric pressure, in an amount of from about zero to about three times the amount of the polymer present in the composition; and volatilizing the propellant at atmospheric pressure and temperature, for foaming the synthetic polymer and forming a foamed structure containing the additive in the cells thereof.
