A process can be used for manufacturing a coloured moulding composition with an improved optical appearance and a particularly high thermal stability. The process involves providing a thermoplastic polymer and adding a colouring preparation, or a liquid composition or a master batch containing the colouring preparation. Injection moulded parts and extruded parts can be composed of the coloured moulding composition.

Process for colouring a thermoplastic polymer

Light scattering polymeric compositions have improved scattering efficiency and improved mechanical properties. The compositions include a polymeric matrix material and at least two different kinds of scattering particles uniformly dispersed therein.

Light scattering polymeric composition with improved scattering efficiency and improved mechanical properties

The present invention relates to a process for producing colored plastics molding compositions with aqueous liquid colors, where an aqueous liquid color is added to a molten plastics molding composition. The present invention also describes a system for conducting the said process.

Process and system for colouring plastics moulding compositions

The present invention relates to weathering-resistant, colored moldings made of poly(alkyl)(meth)acrylate with improved gloss and resistance to mechanical influences acting on the surface of the molding, in particular with improved wipe resistance and improved scratch resistance, and also to molding compositions for producing the same.

Weathering-resistant, colored moldings with improved gloss and wipe resistance

The invention describes transparent plastics mixtures having low-temperature impact resistance composed of a thermoplastic polyurethane (TPU) and of an impact-modified poly(meth)acrylate (PMMA).

Transparent TPU (thermoplastic polyurethanes)/PMMA (polymethyl (meth) acrylate) blends with improved low-temperature impact resistance

The invention relates to the use of polyalkyl(meth)acrylate bead polymers with an average particle size Vthat ranges between 30 and 70 &#x3bc;m for improving the stress cracking resistance of moulding materials containing polyalkyl(meth)acrylate. The invention also relates to moulding materials comprising: a) at least 50 wt. % of an impact resistance modifying agent, which contains at least one polyalkyl(meth)acrylate phase; b) at least 8 wt. % of a polyalkyl(meth)acrylate bead polymer with an average particle size Vthat ranges between 30 and 70 &#x3bc;m; and c) between 0 and 42 wt. % of a polyalkyl(meth)acrylate with a molecular weight ranging between 20,000 and 350,000 g/mol, whereby the wt. % of the components a) to c) amounts to 100 wt. %, and to moulded bodies that can be obtained from said materials.

Use of polyalkyl(meth)acrylate bead polymers and moulding material for producing extruded moulded parts with a matt surface

The invention relates to subduedly colored (brown, gray, black, green), infrared reflecting PMMA compounds which can be applied to other plastic compounds as an IR barrier layer.
