ABSTRACT:
Disclosed is a process for producing a carpet backsized with a backing composition. The composition contains a resin component with ethylene/vinyl acetate being the principle compound and an ethylene/alpha-olefin copolymer constituting the remainder. In addition, the composition includes an inorganic filler in an amount of from 25 to 75% by weight and a dispersing agent that is atactic polypropylene. This composition is formed by kneading and pelletizing the inorganic filler and dispersing agent to form a master batch which is in turn dry-blended with the resin component of the composition, followed by extrusion through T-dies into a sheet and applied, while still melted, to the underside of a carpet base material and cooled.
