SCRATCH-RESISTANT, IMPACT-RESISTANT POLYCARBONATE MOULDING COMPOSITIONS WITH GOOD MECHANICAL PROPERTIES I.

摘要

The present invention relates to scratch-resistant, impact-resistant polycarbonate (PC) compositions and moulding compositions which have good mechanical properties and a high resistance to chemicals coupled with good flameproofing properties, and show improved flow properties during processing, comprising A) 10 - 90 parts by wt. of aromatic polycarbonate and/or aromatic polyester carbonate, B) 0.5 - 30 parts by wt. of rubber-modified graft polymer, C) 0 - 40 parts by wt. of vinyl (co)polymer (C.1) and/or polyalkylene terephthalate (C.2), D) 0.1 - 50 parts by wt. of hollow ceramic spheres, E) 0.2 - 5.0 parts by wt. of at least one polyorganosiloxane, F) 0 - 20 parts by wt. of at least one phosphorus-containing flameproofing agent, G) 0 - 10 parts by wt. of at least one further additive, wherein all the parts by weight stated are standardized such that the sum of the parts by weight of all the components A+B+C+D+E+F+G in the composition is 100. The present invention furthermore relates to a process for the preparation of the compositions and their use for the production of shaped articles, in particular housings of flat screen apparatuses.
