    摘要: A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20.degree. C. but is not a solvent at 20.degree. C. (though it is at 215.degree. C.) for polyethylene terephthalate. The last-named is a crystallizable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.

    摘要: A process for the production of a high modulus filament of polyethylene which comprises heating high density polyethylene to a temperature above its melting point, extruding the polymer to form a filament, subjecting the filament immediately after extrusion to a tension under such conditions that the filament is shaped without substantial orientation of its molecules, cooling the filament at a rate of cooling in excess of 15.degree. C. per minute, and drawing the filament to a high draw ratio.This is a continuation of application Ser. No. 860,999, filed Dec. 15, 1977, abandoned, which is a continuation of Ser. No. 553,656, Feb. 27, 1975, now abandoned.
