PURPOSE:To obtain the titled composition which can give a molding which can be colored in any desired color and is excellent in antistatic property, by adding a phosphoric ester and BaCl2 to a polymer component comprising a PVC resin and an acrylonitrile/butadiene copolymer. CONSTITUTION:The titled composition is obtained by adding 5-100pts.wt. normally liquid volatile phosphoric ester (e.g., tricresyl phosphate), BaCl2 powder of a particle size <=80 mesh and, optionally, a plasticizer such as DOP and other additives to 100pts.wt. polymer component comprising 95-20wt% PVC resin having an average degree of polymerization >=2,000 and a vinyl chloride content >=50wt% and 5-80wt% acrylonitrile/butadiene copolymer. This composition is molded into a sheet and this sheet is used an antistatic sheet on a floor or a desk or as a first sheet which is laminated with a second sheet comprising a resin composition formed by mixing, e.g., a rubber or a plastic with, e.g., carbon black and having a still larger electric conductivity to obtain the titled electroconductive floor sheet.
