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.

The present invention relates to polycarbonate compositions comprising

Impact-modified polycarbonate compositions having a good combination of natural color, hydrolytic stability and melt stability

The present invention relates to moulding compositions of polycarbonates and graft polymers and optionally further additives and components, which have, in addition to a high resistance to chemicals, a good resistance to heat, in particular a low tendency towards yellowing and a low tendency towards degradation when exposed to heat. In a particular, flameproofed embodiment, the after-burn time in a UL94 classification is furthermore reduced.

PC/ABS compositions having a good resistance to heat and chemicals

The present invention relates to a composite component comprising i) a support made of a thermoplastic composition comprising A) at least one polymer selected from the group consisting of aromatic polycarbonates, aromatic polyester carbonates, aromatic polyesters, and mixtures thereof, in an amount of from 20.0 to 85.0 parts by wt., based on the sum of components A and B; B) at least one rubber-modified vinyl (co)polymer in an amount of from 15.0 to 80.0 parts by wt., based on the sum of components A and B, and with a rubber content [R] of at least 25.0 parts by wt., based on component B; and C) at least one polymer additive in an amount of from 0 to 30.0 parts by wt., based on the sum of components A to C; and ii) at least one polyurethane layer, wherein the thermoplastic composition comprises a total rubber content [R], of at least 12 parts by wt., based on the sum of components A to C.

Composite components with improved adhesion of polycarbonate/polyester compositions and polyurethane

The present invention relates to flame resistant molding compositions comprising polycarbonates and graft polymers which, in addition to good flow properties, exhibit good (notched) impact strength and high chemical resistance with a UL94V-0 classification at 1.5 mm. These molding compositions are particularly suitable for thin-walled housing parts in the electrical and electronics sector.
