Splet11. maj 2024 · The PMPU films exhibited higher thermal stability than that of the pure PEEU film. With the PMEH content increasing from 5 to 20 wt%, the PMPU films also possessed satisfied tensile properties with ultimate stress of 22.9–15.8 MPa and strain at break of 925–820%. ... Based on the fundamental properties of PC-containing polymers, the MPC ... SpletLiquid crystalline block copolymers that incorporate both PHTH-6 mesogenic units and polycarbonate (PC) segments in the main chain were synthesized by polycondensation in solution of hydroxyl-terminated PC and acid-chloride-terminated PHTH-6. The copolymer compositions were determined from 1H-NMR data. The structure, thermal properties, as …

The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications equipment, SpletA series of blends of Acrylonitrile-Butadiene-Styrene (ABS) and Polycarbonate (PC) were prepared and some of their thermal and mechanical properties were determined. The Young’s modulus changed gradually and monotonically with the polycarbonate content. This effect was tentatively explained as the antiplasticization of the PC which is ascribed … Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, … Prikaži več Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example … Prikaži več Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate eyewear Prikaži več Polycarbonates were first discovered in 1898 by Alfred Einhorn, a German scientist working at the University of Munich. However, after 30 years' laboratory research, this class of materials was abandoned without commercialization. Research resumed … Prikaži več Phosgene route The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2.
