The present invention provides a vinyl chloride polymer composition which comprises (i) a vinyl chloride polymer (a) and (ii) a block copolymer (b) having a polymer block (I) comprising of a block copolymer, which may be hydrogenated, of an aromatic vinyl compound polymer block and a conjugated diene polymer block, and a polymer block (II) of a polyurethane, in a specific weight ratio. The vinyl chloride polymer composition of the present invention has non-tackiness, excellent handling properties, favorable flexibility and mechanical properties, and favorable melt-adhesiveness to other materials, and shows no migration of the component serving as a plasticizer. The vinyl chloride polymer composition of the present invention can be applied for various uses such as a production of various molded articles and a production of a laminated structure with other materials.
A vinyl chloride polymer composition comprising (i) a vinyl chloride polymer (a) and (ii) a block copolymer (b) having a polymer block (I) of a block copolymer, which may be hydrogenated, of an aromatic vinyl compound polymer block and a conjugated diene polymer block, and a polymer block (II) of a polyurethane, in an amount such that the weight of the vinyl chloride polymer (a) and that of the block copolymer (b) satisfy the following equation (1):
