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

A reactive mixture for coating mouldings by means of reaction injection moulding, containing at least 40% by weight of (meth)acrylates having at least two double bonds. The reactive mixture contains at least one photoinitiator and at least one thermal initiator. The present invention furthermore describes a coated moulding including a moulding which is obtainable by injection moulding processes and includes at least one polymer selected from polymethyl methacrylate, polymethylmethacrylimide, styrene-acrylonitrile copolymer, styrene-maleic acid copolymer and polymethyl methacrylate copolymers, and a coating which is obtainable by polymerization of (meth)acrylates having at least two double bonds. The coating has an adhesive strength rating of not more than 1 according to the cross hatch test and a decrease in gloss at 20&#xb0; after a scratch resistance test according to ASTM 1044 (12/05) (applied weight 500 g, number of cycles=100) of not more than 10%.

Reactive mixture for coating molded objects by means of reaction injection molding and coated molded object

A reactive mixture for coating moldings by reaction injection molding includes at least 40% by weight of (meth)acrylates having at least two double bonds. The reactive mixture also includes at least one photoinitiator and at least one thermal initiator. Furthermore, a coated molding includes a molding obtainable by injection molding processes. The molding includes polymethyl methacrylate, polymethylmethacrylimide, styrene-acrylonitrile copolymer, styrene-maleic acid copolymer, polymethyl methacrylate copolymer, or a combination thereof. A coating is obtainable by polymerization of (meth)acrylates having at least two double bonds, the coating having an adhesive strength rating of not more than 1 according to the cross hatch test and a decrease in gloss at 20&#xb0; after a scratch resistance test according to ASTM 1044 (12/05) (applied weight 500 g, number of cycles=100) of not more than 10%.

The invention relates to a novel UV-protective and weather-resistant package for surface protecting films for polyvinyl chloride window profiles made of poly(meth)acrylate. Matrix plastics having great molecular weights are used in order to obtain great weather resistance of the surface protecting films.

PMMA film featuring particularly great weather resistance and great UV protection

The invention relates to a moulding composition, comprising a) 50 to 99.9% by weight of a matrix composed of a thermoplastic polymer and b) from 0.1 to 50% by weight of a matting agent in the form of a (meth)acrylate copolymer dispersed in the matrix, characterized in that the matting agent is a (meth)acrylate copolymer which has been prepared from the following monomers,

Molding material containing a matting agent

The invention relates to a method for separating transition metals from polymers. According to the invention, a solid polymer containing transition metals is treated with an extracting agent, the duration of the treatment and the extraction temperature being selected in such a way that the transition metal content is reduced by at least 30 wt. %.
