The present invention relates to impact-modified polylactic acid/polycarbonate compositions, containing

Flame retardant polycarbonate compositions

The present invention relates to a polycarbonate composition comprising polyalkyl(alkyl)acrylate having a specific molecular weight and an impact modifier, as well as to moulded bodies obtainable from these compositions. Compositions according to the present invention exhibit superior properties, in particular with respect of low-temperature strength and melt flowability.

Polycarbonate blends having low-temperature impact strength

The present invention relates to flame resistant molding compositions comprising polycarbonates and graft polymers which, in addition to good flow properties, exhibit good (notched) impact strength and high chemical resistance with a UL94V-0 classification at 1.5 mm. These molding compositions are particularly suitable for thin-walled housing parts in the electrical and electronics sector.

Flame-retardant PC/ABS compositions having good impact strength, flowability and chemical resistance

The present disclosure relates to impact-modified polycarbonate compositions which comprise a graft polymer containing silicone/acrylate composite rubber as the graft base, wherein the content of silicone rubber is 65-95 wt. % (based on the graft base), talc having a dvalue (also called 'top cut') of less than 20 &#x3bc;m and phosphorus-containing flame retardant, the use of the polycarbonate compositions for the production of shaped articles and the shaped articles themselves. The compositions and moulding compositions according to the disclosure have an optimum combination of good flameproofing, good resistance to chemicals and hydrolysis and good mechanical properties (i.e. in particular a high E modulus and high notched impact strength a).

Flame retardant impact-modified polycarbonate compositions

The present invention relates to flame-protected impact-modified polycarbonate compositions, wherein the compositions are free of rubber-free polyalkyl (alkyl)acrylate.
