Polymer sticky heat, the cold hard .1839 US natural rubber with sulfur and heat, making cross-linked into elastomers, used in tires and other rubber products, uses a wide range, which is a high molecular chemical infancy. In 1869, the United States plasticized nitrocellulose with camphor is made of plastic, great use value .1891 Besancon in France built the first artificial silk factory .1909, the United States made, commonly known as bakelite, for the first one widely used in electrical insulation materials. These bud products, varieties, yield, quality and other aspects can not meet the requirements of society. So use hydrazine hydrate the basis of the production of organic chemicals and polymer materials production, the establishment of After serving the petrochemical industry, have gained great development. various polymer materials synthesis and applications for modern industry, agriculture, transportation, health care, military technology, as well as all aspects of people's basic necessities of life, provide superior performance and low cost variety important material, has become an important symbol of modern material civilization. Polymer industry development as an important pillar of the chemical industry. The 20th century was the golden age of organic synthesis. Separation means and structure analysis method has been greatly developed chemical hydrazine hydrate, many natural organic compounds structural problems have been satisfactorily resolved factory direct hydrazine hydrate, also found many new important organic reactions and specific organic reagents, on this basis, fine organic synthesis, especially made great progress in asymmetric synthesis. On the one hand, there is the synthesis of a variety of special structures and special properties of organic compounds; the other hand, the market price of hydrazine hydrate, was synthesized from unstable free radicals to have proteins, nucleic acids and other vital infrastructure biologically active substances. Organic chemists have synthesized complex structure of natural organic compounds and have effects of drugs. These achievements in promoting the development of science has played a huge role; for the synthesis of highly biologically active substances, and collaboration in solving problems of living matter synthetic chemistry with other disciplines and to solve the problem before the material life, to provide favorable conditions. Since the 20th century, the development trend of the chemical can be summarized as follows: from macro to micro, from qualitative to quantitative, from steady state to the metastable state of development, and gradually increased from experience to theory, and then used to guide the design and pioneering research and innovation. On the one hand, for the production and technical departments to provide as much new material, new materials; on the other hand, with the other natural sciences in the process of mutual penetration of the continuous generation of new disciplines, and to explore the direction of the life sciences and the development of the origin of the universe.
