ABSTRACT:
A process is disclosed for obtaining olefin-polar comonomer resin in fibrous form. According to the invention, an olefin-polar comonomer resin such as an ethylene-vinyl acetate copolymer is vigorously agitated in molten form in water in the presence of a resin dispersion-forming amount of an alkali metal soap such as sodium stearate and a fiber-forming amount of base such as sodium hydroxide at a temperature below the degradation temperature of the resin to provide a dispersion of said resin in which a substantial number of the individual resin particles are in the form of a fiber possessing an average length of from about 50 to about 2500 microns and an average length to diameter ratio of at least about 3:1. Following cooling of the dispersion to below the solidification point of the resin, the resin fiber may be recovered employing known and conventional means, e.g., filtration, centrifugation, etc.
