Abstract

1,223,673. Polymer solution. J. P. BRENNAN. 23 Feb., 1968 [23 Nov., 1966], No. 52536/66. Heading C3R. A polymer solution comprises (i) an isocyanate-modified polyester containing free OH groups, (ii) an unmodified polyester, (iii) an organic solvent-soluble grade of a polyurethane rubber, (iv) a diisocyanate/polyol reaction product containing free NCO groups and (v) a catalyst for the isocyanate/reactive hydrogencontaining group addition reaction comprising an organic amine, in a solvent system comprising at least two solvents at least one of which is a solvent for the final polymer material and at least one of which is a non-solvent for the final polymer material. Preferably, at least one of the solvents is water miscible and one non- solvent has a lower rate of evaporation than the solvent or solvents for the final polymer. Suitable solvent systems are tetrahydrofuran and methyl ethyl ketone and alternatively dimethylformamide and acetone.
