Abstract: A transportable polymer-fluid composition and process for making the same is described. The composition comprises (I) a dissolved fluid which at normal temperature and pressure at standard conditions of 0 DEG C. and one atmosphere (STP) is a gas; and (II) a thermoplastic or thermosettable polymer having (a) a plurality of moieties with the intermolecular disruption characteristics of mono, di or tri substituted fluorine on carbon and mono, di or tri substituted methyl on carbon or silicon, in which said carbon and silicon are a part of, or are directly or indirectly covalently attached to, the skeleton of the polymer's main structure, and are each no more than about 12 covalently bonded atoms from the covalent linkage to an atom in the main structure of the polymer, and (b) the properties of (i) enhanced expansivity, (ii) reduced cohesive energy density or (iii) both (i) and (ii), thereby allowing more fluid (I) to be dissolved therein.

Abstract: A process of spraying a polymeric compsn. to form a spray of finely atomised liq. droplets comprises (1) forming in a closed system a liq. mixt. a temp. T0 comprising: (a) a non-volatile fraction contg. at least one polymer that is cable of being sprayed; and (b) a solvent fraction that is partially miscible with (a) and contains an amt. of at least one compressed fluid sufficient, when it is added to (a); (i) to make the viscosity of the mixt. suitable for spraying; and (ii) to let the liq. mixt. form a liq. compressed fluid phase at temp. T0 the compressed fluid being a gas at 0 deg. C and 1 atmos. pressure; and (2) spraying the liq. mixt. by passing it at temp. T0 and spray pressure P, into an orifice, through which the mixt. flows to form a liq. spray, where spray pressure P1 is above the min. pressure P2 at which the liq. mixt. forms a liq. compressed fluid phase at temp. T0, thus passing the liq. mixt. through the liq.-liq. region of the polymer compsn. and compressed fluid during depressurisation.
