The invention relates to a composition for production of a thermoplastic moulding compound, wherein the composition comprises or consists of the following constituents: to the moulding compound itself, to the use of the composition or moulding compound for production of moulded articles and to the moulded articles themselves.

SiCoPC blend containing phosphazene and silicone/acrylate impact modifier

The invention relates to a composition for production of a thermoplastic moulding compound, wherein the composition comprises or consists of the following constituents,

Composition and thermoplastic molding compound having good notch impact strength and improved melt stability

The invention relates to a composition for production of a thermoplastic moulding compound, wherein the composition comprises or consists of the following constituents:

Composition and thermoplastic molding compound having good low-temperature toughness, high gloss, and high processing stability

Compositions are provided comprising A) at least one polymer selected from the group consisting of aromatic polycarbonate and aromatic polyester carbonate, B) at least one mixture comprising at least one butadiene-based graft polymer prepared by emulsion, suspension or solution polymerization and at least one polybutadiene-free vinyl (co)polymer, and C) at least one polymer additive, where the polybutadiene content based on the sum total of the parts by weight of components A and B is 10% to 20% by weight, and where the total content of butadiene-free vinyl (co)polymer from component B based on the sum total of the parts by weight of components A and B is 12% to 23% by weight. Composite components formed from these compositions and a polyurethane layer, which are notable for improved adhesion between the two layers, and a process for producing the composite components are also provided.

Polycarbonate compositions having improved adhesion to polyurethane layers

Flame-retardant polycarbonate-polyester compositions

The present invention relates to compositions and composite components formed from these compositions and a polyurethane layer, which are notable for improved adhesion between the two layers, and a process for producing the composite components.

A masterbatch comprising pigment and demolding agent is provided. The demolding agent is selected from the group comprising low molecular weight polyolefin oils, low molecular weight polyolefin waxes, montan waxes and aliphatic or aromatic carboxylic acid esters of fatty acids and/or fatty alcohols, wherein the pigment content of the masterbatch is from 3 to 70 wt. %, based on the total weight of the masterbatch. The masterbatch is suitable for preparation of a polymer composition having improved pigment dispersion.

Process for improving carbon black dispersion

The present invention relates to flame-retardant, impact-modified polycarbonate (PC) compositions and molding compositions which have good mechanical properties, good resistance to chemicals and high hydrolytic stability. The present application additionally relates to the use of the compositions in the production of molded articles, and to molded articles produced from the compositions.
