摘要:
Multilayered plastic objects are prepared having a core layer of an aromatic polycarbonate in contact with a polymethacrylate film containing a UV absorber. The polymethacrylate film comprises a copolymer of methylmethacrylate and an acrylic or methacrylic ester, (meth)acrylamide, maleimide or mixtures thereof and is compatible with said aromatic polycarbonate at all mixing ratios.

摘要:
The invention relates to the use of polyalkyl(meth)acrylate bead polymers with an average particle size V50 that ranges between 30 and 70 μm 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 V50 that ranges between 30 and 70 μm; 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.
摘要:
The invention relates to a polymer mixture, comprising a) a polymer matrix which is composed of a (meth)acrylate (co)polymer or of a mixture of (meth)acrylate (co)polymers with a Vicat softening point VSP (ISO 306-B50) of at least 104° C. and/or of a (meth)acrylimide (co)polymer, b) an impact modifier which is based on crosslinked poly(meth)acrylates and which does not have covalent bonding to the polymer matrix a), c) from 1 to 15% by weight of plastics particles composed of crosslinked polymers based on polymethyl methacrylate, on polystyrene and/or on polysilicones. The polymer mixture can be used to obtain injection mouldings with matt surfaces and Vicat softening points VSPs (ISO 306-B50) of at least 90° C.

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.
摘要:
Moulding composition, comprising, in each case based on the total weight of the moulding composition,A) from 83% by weight to 99.5% by weight of a polymer matrix which is composed of at least one (meth)acrylimide (co)polymer,B) from 0.5% by weight to 17.0% by weight of ceramic beads,where the melt volume index MVR of the moulding composition, measured to ISO 1133 at 260° C. using 10 kg, is from 1.0 cm3/10 min to 20.0 cm3/10 min.The moulding composition can be used for production of mouldings with a velvet-matt and preferably rough surface. These mouldings are particularly suitable as parts of household devices, of communications devices, of hobby equipment or of sports equipment, or as bodywork parts or parts of bodywork parts in automobile construction, shipbuilding or aircraft construction, or as parts for illuminants, signs or symbols, retail outlets or cosmetics counters, containers, household-decoration items or office-decoration items, furniture applications, shower doors and office doors, or else as parts in the construction industry, as walls, as window frames, bench seats, lamp covers, diffuser sheets, or for automobile glazing.
