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, polycarbonates find many applications. Polycarbonates do not have a unique r… WebPC, a polymer manufactured by eco-friendly non-phosgene process, has excellent impact resistance, heat resistance and transparency.

WebIndustrial plastic granules Source: © Shutterstock BASF and other German industrial firms, such as Bayer, were manufacturing phosgene in significant quantities prior to the outbreak of the first world war, but its development as a chemical warfare agent was rapidly brought to the fore by the Nobel prize winning chemist, Fritz Haber, in 1915. Phosgene is a valued and important industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics. Phosgene is extremely poisonous and was used as a chemical weapon during World War I, where it was responsible for 85,000 deaths. See more Phosgene is the organic chemical compound with the formula COCl2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. It can be thought of as formaldehyde with … See more Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111.8°. Phosgene is a carbon oxohalide and it can be considered one of the simplest acyl chlorides, … See more The reaction of an organic substrate with phosgene is called phosgenation.
