| titleOfInvention | Impact resistant modified polycarbonate compositions for producing metalized moulded articles with homogenous surface gloss |
| abstract | The invention relates to impact resistant modified polycarbonate compositions, comprising: A) 55 to 90 parts by weight (related to the sum of the parts by weight of the components A, B and C) of aromatic polycarbonate and/or aromatic polyester carbonate with a relative solution viscosity, measured in methylene chloride, from 1.20 to 1.30; B) 10 to 45 parts by weight (related to the sum of the parts by weight of the components A, B and C) of rubber-modified component containing B.1) at least one graft polymer, produced in emulsion polymerization, by graft polymerization of B.1.1.) 5 to 95% by weight, related to the sum of B.1.1. and B.1.2., of at least one vinyl monomer at B.1.2) 95 to 5% by weight, related to the sum of B.1.1 and B.1.2, of one or more particulate rubbers as a graft base with glass transition temperatures of < 0°C, B.2) if necessary a rubber-free vinyl(co)polymerizate, B.3) if necessary a graft polymerizate from at least one vinyl monomer on at least one rubber base with a glass transition temperature < 0°C, produced in the mass, solution or mass suspension polymerization method, wherein the graft polymerizates B.1 and B.3 may also contain, due to the manufacture thereof, in addition to graft particles, if necessary, free, i.e. (co)polymerizate of the vinyl monomers which are chemically not bound to the rubber particles and/or which are enclosed in the graft particles in a form that is insoluble in organic solvents; C) 0 to 25 parts by weight (related to the sum of the parts by weight of the components A, B and C) of polymeric additives, characterized in that (i) the rubber ratio of the polycarbonate composition is 1 to 6% by weight, and (ii) at least 40% by weight of the graft particles in component B have a diameter (measured in an ultracentrifuge) of up to 200 nm, which are classified by having a high heat resistance and a good melt flow rate. Furthermore, the moulded articles produced from the composition according to the invention in the die casting method can be metalized, wherein the resulting metalized moulded articles have a surface with a particularly high and in particular homogenous gloss level. Another object of the invention is thus also the metalized moulded articles made of the compositions according to the invention. |
