The invention relates to compositions based on aromatic polycarbonate comprising metal oxide-coated micas as effect pigment, which do not have any significant increase in molecular weight of the polycarbonate, as can be seen from the MVR, under thermal stress. This is achieved by the addition of small amounts of an anhydride-modified α-olefin polymer, optionally in combination with phosphorus-containing thermal stabilizer.

The invention relates to a composition for producing a thermoplastic moulding material, wherein the composition contains the following constituents: A) at least one polymer selected from the group consisting of aromatic polycarbonate, aromatic polyestercarbonate and polyester, B) at least one anhydride-functionalized ethylene-α-olefin copolymer or ethylene-α-olefin terpolymer having a weight-average molecular weight Mw of 50000 to 500000 g/mol determined by high-temperature gel permeation chromatography using ortho-dichlorobenzene as solvent against polystyrene standards, C) a talc-based mineral filler, and also to a process for producing the moulding material, to the moulding material itself, to the use of the composition or of the moulding material for producing moulded articles and to the moulded articles themselves.

An epoxy-curable silicone release coating composition and methods for its preparation and use are provided. The composition contains an inhibited Lewis acid catalyst. Releasing the Lewis acid catalyst from the inhibitor allows the Lewis acid to catalyze cure of the epoxy-groups. The composition can be coated on various substrates and cured to form a release liner.
