    Abstract: Disclosed are a lactone-modified polyvinyl alcohol and a process for the preparation thereof, a polymer composition, a permanently anti-electrostatic resin composition, a lactone-modified resin having hydroxyl groups, and a process for the preparation thereof.
    The lactone-modified polyvinyl alcohol can be used in wide fields owing to capability of freely adjusting a water solubility such as water-soluble, gradually water-soluble, low water-soluble, and water-insoluble by a degree modified by lactone compounds, and owing to possessing both properties in PVA and lactones.
    Furthermore, the lactone-modified polyvinyl alcohol has a property as plasticizers or softening agents, as a result, there can be provided a polymer composition having an excellent property by mixing with hydrophilic polymer or polar polymer.
    Still further, a blend resin composition in which a variety of resins are blended with the lactone-modified polyvinyl alcohol has an excellent permanently-anti-electrostatic property, and the resin composition having a permanently-anti-electrostatic property can be preferably employed as a variety of molded articles such as parts for electric appliances, textiles, films, etc.

    Abstract: An antistatic polymeric composition comprising a base polymer, constituting 20 to 98.9 per cent by weight of the composition, includes both a surface active agent constituting 0.1 to 30 per cent by weight of the composition and an antistatic additive constituting 1 to 50 per cent by weight of the composition. The surface active agent comprises at least one compound selected from an amino, sulphonyl or phosphonyl titanate, zirconate or zircoaluminate and the antistatic additive is a polymer derived from ethylene oxide and at least one other monomer selected from an epihalohydrin, propylene oxide, and a cyclic monomer. The composition preferably contains a compatabilizer. Optionally, the composition may contain a mineral filler, constituting 0.1 to 70 per cent by weight of the composition, such as a metal oxide, for example an oxide of titanium, zinc, tin, antimony or aluminium, a metal silicate, aluminosilicate or carbonate or silicon oxide. The base polymer may be a homopolymer or copolymer of ethylene, propylene or styrene, an aliphatic or aromatic polyester, a polyamide, a polycarbonate or an elastomer or a combination of more than one of these. The antistatic polymeric composition should have surface resistivity of the order of 10¹⁰ ohm/sq.

    Abstract: Provided are: an antistatic agent which is capable of imparting excellent antistatic effect in a small amount and has sufficient persistence and wiping resistance; an antistatic agent composition; an antistatic resin composition; and a molded article. The antistatic agent comprises a polymer compound (E) having a structure in which a block polymer (C) and a polyhydric alcohol compound (D) are bound via an ester bond formed by a carboxyl group of the block polymer (C) and a hydroxyl group of the polyhydric alcohol compound (D), the block polymer (C) having a structure comprising carboxyl groups at both ends, in which structure a block constituted by a polyester (A) having carboxyl groups at both ends and a block constituted by a compound (B) having hydroxyl groups at both ends are repeatedly and alternately bound via ester bonds formed by the carboxyl and hydroxyl groups, and the polyhydric alcohol compound (D) comprising three or more hydroxyl groups.
