PURPOSE:A resin composition excellent in filler dispersibility and capable of forming vehicle carpet backings having a moderate flexural rigidity and a good pile pulling strength, prepared by mixing low-density polyethylene, an ethylene/ vinyl acetate copolymer, and an inorganic filler. CONSTITUTION:100pts.wt. low-density polyethylene (preferably, one having a melt index according to JIS 6760 of about 10-50) is mixed with 15-60pts.wt. ethylene/vinyl acetate copolymer (or its graft copolymer, preferably one having a melt index of about 10-75) and 30-200pts.wt. inorganic filler (e.g., calcium carbonate). These components are mixed preferably as follows. The inorganic filler granulated with the aid of a binder together with the ethylene/vinyl acetate copolymer is pelletized, and the pellets are dry-blended with the low-density polyethylene. |
