Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a block copolymer that can impart permanent antistatic properties to a polyolefinic resin, a polyolefinic resin composition to which permanent antistatic properties are imparted by the block copolymer and a molding. SOLUTION: This block polymer is composed of a polymer block (A) containing 10-100 mol.% quat. ammonium salt group-containing vinyl monomer units (I) and polyalkylene-glycol-chain-containing vinyl monomer units (ii) and having a molar ratio of structural units (I) to structural units (ii) of 1/10 to 1,000/1 and a polymer block (B) having 50-100 mol.% olefin units. The resin composition is prepared by mixing 0.5-20 pts.wt. this block copolymer with 100 pts.wt. polyolefin resin and a molding made from this composition.
