TL;DR: In this article, a flame retardant polycarbonate composition having good mechanical properties and melt stability was proposed. But the properties were achieved by adding small amounts of a fibril forming polytetrafluoroethylene, and an alkali metal salt of an inorganic acid, and a small amount of aromatically bound chlorine or bromine contained in a compound other than an organic alkaline metal or alkaline earth metal salt to a thermoplastic aromatic poly carbonate.
Abstract: The present invention is concerned with flame retardant polycarbonate compositions having good mechanical properties and melt stability. These properties are achieved by adding small amounts of a fibril forming polytetrafluoroethylene, and an alkali metal salt of an inorganic acid, and a small amount of aromatically bound chlorine or bromine contained in a compound other than an organic alkali metal or alkaline earth metal salt to a thermoplastic aromatic polycarbonate.

TL;DR: In this article, the effect of different-sized structures on properties of the polycarbonate surface was investigated in contact angle measurements with water and oleic acid, which was achieved by applying nanoporous anodized aluminum oxide (AAO) membranes, microstructured aluminum foil, or anodic alumina on microStructured aluminum as mold inserts in injection molding.

TL;DR: Deuteron NMR was used in this paper to study phenylene group motions in glassy polycarbonate (PC) as a function of tensile stress and chemical modification, and a special stretching device was constructed allowing the application of forces up to 1500 N during the measurement.
Abstract: Deuteron NMR was utilized to study phenylene group motions in glassy polycarbonate (PC) as a function of tensile stress and chemical modification. A special stretching device was constructed allowing the application of forces up to 1500 N during the measurement. While cold drawing of PC effects motional restrictions equivalent to a temperature shift of 10 K, a reversible strain near the yield point enhances the ring dynamics slightly. Methyl group substitution at the ortho positions gives rise to even more constraints, shifting the onset of fast ring flips by about 180 K.
