    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: Electrically conductive polymeric systems having electrical conductivities greater than 10.sup.-4 S/cm are prepared by a method wherein a polyarylene compound which contains one or more chain members of the formula ##STR1## where n is greater than 1, preferably from 5 to 50, R is a nitrile, acid amide, carboxyl or ester group, R.sup.1 and R.sup.2 are each hydrogen or a nitrile, acid amide, carboxyl or ester group, with the proviso that in each case one of the radicals R.sup.1 and R.sup.2 is hydrogen and the other is a nitrile, acid amide, carboxyl or ester group, and Y is an aromatic radical, preferably phenylene, is doped, in the absence of moisture and oxygen, with from 0.03 to 0.9 mole percent of an electron-attracting or electron-donating complexing agent. The resulting electrically conductive polymeric systems are useful in the electrical industry for the production of solar cells, for converting and fixing electromagnetic radiation and for the production of electrical and magnetic switches and electrical storage devices, and can be used for the antistatic treatment of plastics.

    Abstract: Polyphenylene ether resins having improved properties are described. These resins contain minor effective amounts of an antistatic agent comprising N,N-bis-(2-hydroxyethyl)-N-octyl-N-methyl ammonium para toluene sulfonate salt, preferably with polyethylene glycol ester also present. In addition to serving as an enhancer for the antistatic agent, the polyethylene glycol ester also improves such properties as odor and impact strength.
