    Abstract: The present invention is directed to methods for spraying polymeric compositions with supercritical or subcritical compressed fluids such as carbon dioxide or ethane over a wider range of spray conditions to provide improved spray application quality with reduced emission of solvent. The methods are accomplished by using an elongated spray orifice to transform narrow, fishtail, liquid-film sprays to wider, feathered, decompressive sprays.

    Abstract: A method for admixing a solvent-borne compsn. contg. a high concn. of at least one solid polymer capable of being sprayed as a liq. soln. and at least one compressed fluid as a viscosity reducing diluent which is a ga at STP comprises admixing the solvent-borne compsn. and the compressed fluid together at a pressure P, the compressed fluid has a feed temp., T1, such that at least one compressed fluid is a gas or supercritical fluid and has a solubility parameter of 0.5-4 (cal/cc)1/2, thereby avoiding undesirable pptn. of the solid polymer and consequential plugging of the apparatus.
