    摘要: An olefin resin-based article having good gas barrier properties is disclosed, comprising an .alpha.,.beta.-ethylenically unsaturated carboxylic acid-grafted polyolefin (e.g., maleic anhydride-grafted polypropylene) having formed thereon an inorganic oxide deposite film, wherein the grafted polyolefin has an unsaturated carboxylic acid unit concentration of from 0.01 to 10% by weight, with or without an anchor coat being provided between the grafted polyolefin and the inorganic oxide film. The article suffers from no reduction in gas barrier properties even when heat or stress is applied thereto and is therefore useful as a wrapping or packaging material in the production of pouch-packed foods and IC packages.

    摘要: A process of purifying maleic anhydride graft polyolefin comprising the steps of adding an aqueous solution of alkali initial hydroxide to a solution of maleic anhydride graft polyolefin containing unreacted maleic anhydride which is dissolved in an organic solvent at a temperature from 80.degree. C. to 160.degree. C., thereby precipitating maleic anhydride graft polyolefin particles to make a W/O emulsion; stirring the W/O emulsion while maintaining the temperature at a same temperature as above for less than 2 hours, thereby selectively forming the alkali metal salt of unreacted maleic anhydride; adding the aqueous solution of alkali metal hydroxide to the W/O emulsion to convert the W/O emulsion into an O/W emulsion; separating the maleic anhydride draft polyolefin particles, and washing the maleic anhydride graft polyolefin particles with water.
