PA尼 龙(国外英文资料) The main varieties of nylon of nylon 6 and nylon 66, absolute dominant position, followed by nylon 11, nylon 12, nylon 610, nylon 612 and nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new varieties of nylon 6I, nylon 9T and nylon MXD6 (special barrier resins), nylon modified variety quantity, such as reinforced nylon, monomer casting nylon (MC nylon), reaction injection molding (RIM) aromatic nylon, nylon, nylon, high impact (Supertough nylon), electroplating conductive nylon, nylon, flame retardant nylon, nylon and other polymer blends and alloy, meet various special requirements, widely used in metal, wood and other traditional materials as substitutes for various structural materials. Nylon is the most important engineering plastic, and its output is the first in the five major engineering plastics. Nylon [1], a polyamide fiber (nylon), is a statement. It can be made into staple fiber or staple fiber. Nylon was developed by Carlo Seth, an outstanding scientist in the United States, and a research team under the leadership of Carothers, the first synthetic fiber in the world. The appearance of nylon gives a new look to the fabric, and its synthesis is a major breakthrough in the synthetic fiber industry. It is also an important milestone in polymer chemistry. In 1928, the DuPont Co, the largest chemical company in the United States, founded the Institute of basic chemistry, and Dr. Carlo Seth, 32, was employed as head of the institute. He is mainly engaged in the study of polymerization. He first studied polycondensation of bifunctional molecules, through esterification condensation diols and two carboxylic acids, the synthesis of polyester long chain, high relative molecular mass. In less than two years, Carlo Seth in the preparation of linear polymers especially polyester, has made important progress, will increase the molecular weight of polymer to 10000 to 25000, he put the relative molecular weight of more than 10000 polymers called polymers
