    摘要: Poly(alkylene terephthalate) molding materials which contain, as the stabilizer, a diepoxide of molecular weight from 200 to 2,000, and a catalyst which is an alkali metal salt of a chelating agent possessing one or more --N(CH.sub.2 --COO.sup.-).sub.2 groups in the molecule. Preferred catalysts are trisodium nitrilotriacetate and tetrasodium ethylenediaminetetraacetate. The molding materials may be used for the manufacture of moldings, films, monofilaments and fibers.

    摘要: Secondary batteries with aqueous acid solutions of lead salts as electrolytes and inert electrode base plates also contain redox systems in solution. These systems have a standard potential of from -0.1 to +1.4 V relative to a standard hydrogen reference electrode, do not form insoluble compounds with the electrolytes and are not oxidized or reduced irreversibly by the active compositions applied to the electrode base plates, within their range of operating potentials.

    摘要: Thermoplastics reinforced with glass fiber mats contain from 10 to 60% by weight of such mats and from 5 to 60% by weight of a finely divided inert filler, the sum of the percentages by weight of glass fiber mats and filler being not greater than 70% by weight. The inert filler is a talc, having a foliated crystalline structure, which has a mean flake thickness of not more than 5 .mu.m and a ratio of mean flake diameter to mean flake thickness of from 5:1 to 500:1. When processing the thermoplastic filled with talc and glass fiber mats, homogeneous impregnation of the glass fiber mats with the filled thermoplastic is achieved.
