Description

technical field [0001] The invention belongs to the technical field of polycarbonate materials, in particular to a polycarbonate material with high weather resistance and stress cracking resistance. Background technique [0002] Polycarbonate (PC) is the general term for polyester corresponding to carbonic acid, which is divided into aliphatic, aliphatic-aromatic and aromatic polycarbonate, among which aromatic polycarbonate is listed as the top five engineering plastics because of its excellent comprehensive performance. one. Among aromatic PCs, bisphenol A PC is the most widely used and is widely used to prepare PC blends. Because polycarbonate has excellent properties such as high impact strength, creep resistance, good dimensional stability, heat resistance, and insulation, it has become a leader in general engineering plastics, and its development speed ranks first. However, many polycarbonate polymers are brittle especially at low temperatures, and while polycarbonat...
