    摘要: The invention provides a low gloss polymer blend comprising an aromatic carbonate without reactive groups, a polymer or copolymer having a reactive epoxygroup and an aromatic carbonate polymer or copolymer having a reactive group which react with the epoxy group. Optionally, the composition may contain further usual compounds, such as polymeric materials which are normally used to modify the mechanical properties of polycarbonate, particularly rubbery or non-rubbery polymeric materials containing units of a styrene; also additives like colorants, flame retarding agents may be routinely incorporated.
