Abstract:
A liquid chemical formulation comprising:polycarbonate material; anda liquid (a) capable of dissolving the polycarbonate material to a concentration of at least 1% by mass of the liquid formulation at 20.degree. C. and 1 atmosphere, (b) having a boiling point of at least 80.degree. C. at 1 atmosphere, and (c) having a protonated from whose acid dissociation constant is greater than 10.sup.-8 at 20.degree. C. and 1 atmosphere, the polycarbonate material being dissolved in the liquid so as to be present in the liquid at a higher mass fraction than any other constituent present in the liquid, the polycarbonate material also constituting largely all the solid material present in the liquid.
