Stable pigmented polycarbonates
Injection moulding cpds. consists of thermoplastic aromatic polycarbonates with 0.1 to 30%, of the total wt. of polycarbonate and pigments, of a pigment, and 5 to 100% of a polymer from an unsaturated olefinic monomer. The polymer pref. contains nitriles or esters of carboxylic acids or epoxy gps. T...

| description | Injection moulding cpds. consists of thermoplastic aromatic polycarbonates with 0.1 to 30%, of the total wt. of polycarbonate and pigments, of a pigment, and 5 to 100% of a polymer from an unsaturated olefinic monomer. The polymer pref. contains nitriles or esters of carboxylic acids or epoxy gps. The polymer pref. consists of a copolymer of (a) (meth)acrylic acid esters with monohydric aliphatic or cycloaliphatic alcohols containing 1 to 6C atoms, (b) monovinylic aromatic cpds. and (c) glycidyl esters of (meth) acrylic acid. The pigment consists of 0.1 to 30% of a mineral oxide, sulphide or sulphate, or carbon black. The polycarbonate is pref. of bisphenol A. The cpds. are stable to humidity during moulding and have improved colour brightness. |
