    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.

    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.
