Abstract:
The invention relates to anti-electrostatic polycarbonate compositions which are chlorine and bromine free and non-inflammable and are characterized by good mechanical and thermal properties and by problem-free workability in an injection molding process, that is, good flowability of the molten mass and low tendency to juicing. The invention also relates to the utilization of the inventive polycarbonate molding materials in the production of all sorts of molded bodies and molded parts and to the molded bodies and parts.
Abstract:
The invention relates to thermoplastic moulding materials on the basis of polycarbonate and/or polyester carbonate. Said thermoplastic materials contains graft polymer and phosphorous compounds of general formula (I). Said graft polymer and phosphorus compounds are produced by means of a mass, dilution or mass suspension polymerisation process.
