Abstract

Procedure for the production of sheets from copolymers of vinyl chloride and vinyl acetate by thermoplastic transformation, characterized in that copolymers of vinyl chloride and vinyl acetate are extruded to form sheets in worm extrusion presses with 31 to 50% proportion of vinyl acetate and a K index according to Fikentscher of 40 to 70, with solid stabilizers and possibly solid lubricating agents and/or solid fillers at temperatures between 110 and 180ºC.
