    摘要： The present invention is concerned with a process for the production of high molecular weight thermoplastic ppolycarbonates having improved flame resistance and in conjunction with glass fibres, improved mechanical properties and the polycarbonates so produced. A solution polycarbonate is reacted with an alkali metal salt soluble in the melt of the polycarbonate until the Staudinger Index has increased by about 3 to 30 cm.sup.3 /g. This usually requires about 0.0001 to 0.1 wt. % of the salt, based on the weight of polycarbonate and a temperature of about 250.degree. to 400.degree. C for between about 1 and 30 minutes. In a preferred embodiment the reaction is conducted in a self-cleaning twin screw extruder.

    摘要： This invention provides spheres of high molecular weight thermoplastics filled with short glass fibers which may be easily metered, incorporated into thermoplastic resins or fused into glass mats or shaped articles. It also provides a method of producing such spheres by treating glass fibers with a dilute (1 to 30 wt% strength) solution of the plastic having a viscosity of less than 1,000 cP. The fibers are rotated with the polymer solution and the solvent is subsequently evaporated off. Preferably, the coating plastic is a high molecular weight thermoplastic.

    摘要： Carbonate-modified copolyesters which are suitable for the production of mouldings by injection moulding or for the production of pipes, films and fibers by extrusion, can be obtained by reacting aromatic dicarboxylic acids or their ester-forming derivatives and carbonic acid esters of dihydric aliphatic alcohols which have carbonic acid ester groupings in the molecule and hydroxyalkyl end groups.
