METHOD FOR CONTINUOUSLY EXTRUDING A POLYMER RESIN

Document Type and Number:

WIPO Patent Application WO/2011/122870

Kind Code:

A2

Abstract:

The present invention relates to a method for continuously extruding a crystalline or non-crystalline polymer resin, wherein the method comprises: a) a step of injecting a resin composition, containing a polymer resin and an additive, into an extruder; b) a step of melting the mixed composition and delivering the molten polymer resin to a die; c) and a step of injecting organic/inorganic coating substances, for lubricating the surface of the polymer resin, into the die, coating the surface of the molten polymer resin, and extruding the molten polymer resin from the die to thereby produce a molded article.
