A thermoplastic molding composition comprising, (A) an aromatic polycarbonate; (B) a single rubber-free copolymer, e.g., of styrene and acrylonitrile; (C) a first graft polymer; (D) a second graft polymer; and (E) a wax, is described. The single rubber-free copolymer (B), and first and second graft polymers (C) and (D) are prepared from a specific selection of graft phases and graft bases. The graft base of the first graft polymer (C) comprises a crosslinked, particulate elastomer having an average particle diameter of 0.05 to 0.5 microns. The second graft polymer (D) has an average particle diameter of 0.6 to 20 microns. The thermoplastic compositions of the present invention are well suited for the preparation of molded articles that may be metalized over at least a portion of their surface by means of an electroless plating process. Such electroless plated articles are characterized as having improved heat resistance and adhesion of the metal plating.

Thermoplastic polycarbonate molding composition containing a rubber free copolymer and a combination of graft polymers

A method of producing ABS moulding compositions wherein a solution of polymers in group (A) solvents is gradually supplied to a polymerizing mixture of previously-formed soluble rubber, aromatic mono-alkenyl compounds, ethylenically unsaturated nitrites, optional other copolymerizable compounds and optionally a group (B) solvent or a mixture of group (A) and group (B) solvents, the gradual addition of the polymer solution to the polymerizing mixture being started before the beginning of phase inversion and at a monomer conversion rate of 5 to 15% and a viscosity of the polymerizing mixture of less than 20 Pa.sec with simultaneous continuation of polymerization, the group (A) solvent is an aliphatic (C.sub.1 -C.sub.8) or cycloaliphatic alcohol, ketone, ether, ester and/or nitrile, and the group (B) solvent is an aliphatic (C.sub.4 -C.sub.10), cycloaliphatic and/or aromatic hydrocarbon.

Method of producing ABS moulding compositions

Compositions of the ABS type for processing by extrusion and deep drawing

N-Substituted cyclic imides are obtained by reacting a cyclic acid anhydride with an amine in the presence of a solvent and an acid catalyst at 80.degree. to 200.degree. C. and with removal of the water formed, it being particularly advantageous to carry out this reaction in the presence of a stabilizer and an inert, dipolar aprotic cosolvent, optionally to add an inert organic solvent of low or zero polarity to the reaction mixture present after the reaction, to add a non-aqueous base in an amount of 0.5 to 50% by weight, based on the cyclic anhydride of the formula (II) used, and to separate off the precipitate formed to give a filtrate containing the N-substituted cyclic imide.
