The invention relates to a composite component that has improved bonding properties and includes a substrate (i) made of a thermoplastic polymer blend composition, and a coating (ii); in a layer located 5 to 10 &#x3bc;m below the boundary surface between the substrate (i) and the coating (ii), the substrate (i) has a dispersed, non-lamellar phase structure. The invention also relates to a method for manufacturing the composite component.

Composite component

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

Glass-fibre-reinforced polycarbonate moulding compositions with improved toughness

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.

Described herein are polymer compositions comprising Compositions of the present invention are distinguished by an improved surface after heat-moisture storage and are suitable in particular for the production of moldings with a high gloss finish that demand a class A surface, which have optionally been subjected, in whole or in part, to a further surface treatment step involving e.g. lacquering, in-mold decoration, or metallization by vacuum deposition or galvanization.

Abs compositions with improved surface after heat-moisture storage

Multi-layer composites comprising: (a) a first scratch-resistant coating layer comprising a first coating (primer); (b) a thermoplastic layer; and (c) a second scratch-resistant coating layer comprising a second coating (primer); wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are disposed on opposing sides of the thermoplastic layer; wherein the first coating and the second coating are not the same; and wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are selected such that a multi-layer composite having the first scratch-resistant layer disposed on both sides of the thermoplastic layer has a lower critical impact speed for tough/brittle transition at &#x2212;30&#xb0; C. according to DIN EN ISO 6603-1 than a multi-layer composite having the second scratch-resistant layer disposed on both sides of the thermoplastic layer; processes for producing the same; and uses therefor.
