The polyarylate contains a high-density aromatic ring in the main chain, and has self-extinguishing properties and high heat resistance. This polymer has a low crystallinity and is therefore very transparent. General molding processes such as injection, extrusion, and blow molding can be employed. Its main features are as follows: (1) The main chain contains a high-density aromatic ring. After heat-strengthening with glass fiber, the heat resistance is high. Under heavy load, the heat distortion temperature is 175 ° C. If the temperature is raised at 10 ° C / min, the weight loss is only 5% at 443 ° C. . (2) Excellent impact strength, large yield elongation, and good elastic recovery. (3) Transparent (4) Large surface hardness (5) Excellent insulation
Dimethyl Malonate is a common organic reagents, dimethyl malonate is an important raw material for the production of pharmaceutical pipemidic acid. Foreign dimethyl malonate is mainly used as non-ethoxymethylene process production of pipaic acid raw materials, and orthoformate and urea reaction production of pipemidic acid
