Abstract

Procedure for the recovery of gummy polymers or copolymers from their solutions in hydrocarbon solvents, comprising the operations of mixing the hydrocarbon solution of the gummy polymers or copolymers with water and of distilling in steam the resulting mixture in the presence of a dispersant of the lumps of the polymer or copolymer, thus obtaining a dispersion of the polymer or copolymer in water and extracting, together with the steam, all the solvent from the hydrocarbon solution, characterized in that a biodegradable surfactant is used as dispersant.
