Abstract: 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.

Abstract: - 10 - O.Z. 0050/36564 Nylons are prepared by a continuous process in which, in a precondensation zone, an aqueous solution of a salt of a dicarboxylic acid of 6 to 18 carbon atoms and a diamine of 6 to 18 carbon atoms is heated to 250-300.degree.C under superatmospheric pressure, with simultaneous vaporization of water and formation of a prepolymer, the prepolymer and the vapor are separated, and the former is fed into a polycondensation zone and condensed under superatmospheric pressure of from 1 to 10 bar and at from 250 to 300.degree.C, wherein the aqueous salt solution is condensed under superatmospheric pressure of from 1 to 10 bar in the first third of the tubular precondensation zone provided with baffles, until the degree of conversion is not less than 93%, and the prepolymer and the vapor phase are brought into intimate contact with one another in the remaining two thirds of the precondensation zone.

Abstract: - 8 - O.Z. 0050/36394 Polylactams are prepared continuously by a process in which a lactam containing from 1 to 25% by weight of water is heated in a prepolymerization zone under a pressure of from 1 to 10 bar at from 220 to 280.degree.C for from 1 to 10 minutes, water being vaporized at the same time, with the proviso that the degree of conversion on emergence from the prepolymerization zone is not Less than 85%, the prepolymer and the vapor are separated continuously, and the prepolymer is passed into a polymerization zone and is polymerized further under superatmospheric pressure at from 240 to 290.degree.C.

Abstract: A flameproofed nylon molding composition which can be processed by thermoplastic methods and which contains, as the flameproofing agent, from 5 to 30% by weight of brominated styrene oligomers and a synergistic metal oxide. The compositions may be used for the manufacture of injection moldings for the electrical industry.
