    摘要: Flame-resistant polycarbonate molding compositions containing halogen-free sulphonic acid salts of aromatic aldehydes or acetals of these aldehydes in quantities of about 0.005 to 10% relative to the total weight of the composition are disclosed. The compositions optionally further containing inorganic sulphates, exhibit flame retardance and little tendency to dripping in comparison to prior art compositions.

    摘要: New aromatic polyesters and polyester-carbonates are prepared by the reaction of bisphenols of the formula ##STR1## wherein R.sup.3 and R.sup.4 independently of each other represent C.sub.1 -C.sub.4 alkyl group or a halogen atom, i and k denote zero or an integer 1 to 4, and X.sub.1 and X.sub.2 represent fluorine by the two-phase boundary process in an aqueous-alkaline phase with iso- or tere-phthaloyl dichloride. The polyesters and polyester carbonates according to the invention can be processed to form shaped articles by extrusion molding or in an extruder, applied in the form of solutions, or spun to fibers from melt or solution.
