Abstract

The process for recovering hydroxyethylcellulose from cuts of film coated with a hydrophobic resin, which comprises subdividing the film into small particles and forming a suspension of the particles in a dilute aqueous solution of sodium hydroxide, passing the suspension through a device mechanical cutting which further reduces the size of the particles, resulting in a rapid dissolution of the hydroxyethyl cellulose in the aqueous solution, and separating the aqueous solution of hydroxyethyl cellulose from the undissolved resin particles.
