It is accepted that the plastic industry started with the commercial production of nitrocellulose (1868). Following nitro cellulose, phenol-formaldehyde-based polymers, which are the second synthetic plastic in history, have been developed. Their production took place approximately 40 years after this date. Polymers, which are the basic building blocks and raw materials of these and other plastic materials that follow, emerged as a result of some trial studies in the second half of the 19th century, and many of them were discovered by chance.Basically, we know that there are 3 different materials in nature and that they are widely used. These; polymeric materials, metallic materials and ceramic materials.Those who easily hand over form metals. Nonmetals form polymers. The mixture of metallic and non-metallic elements leads to ceramics. There are the following differences between these three basic materials. Metals conduct heat and electricity. They are bright, usually hard, and react by donating electrons. Their density is higher than 1. Polymers do not conduct electricity and heat well, they are usually solid or dull looking. Their density is small, around 1, they are light. Metals or polymers are preferred for different applications especially because of these differences. Polymers are preferred over metals. Thus, plastic with different properties was produced from polymer materials.Annual consumption of polymer materials is more than 150 million tons / year for all countries of the world. Consumption in our country is approximately one percent of this amount. Cellulose, starch, natural rubber and so on. Natural polymers have left their places to semi-synthetic and later synthetic polymers due to the difficulty of processing and lack of some physical, chemical and mechanical properties. The first polymer material was celluloid discovered by S. Hyatt in 1863. Celluloid, a semi-synthetic polymer, is obtained from cotton cellulose. However, the plastics industry started in 1989 with the production of bakelite industry-wide by L. Baekeland. Bakelite, a phenol formaldehyde resin, has been used to make plastic products such as telephone handsets. Until 1924, polymer structures were thought to consist of small molecules in the form of "colloid aggregates". As a result of his extensive investigations, H. Staudinger showed that plastics consist of macromolecules in the form of chains and that these molecules consist of small units covalently linked to each other. Based on the idea mentioned above, the polymer industry developed rapidly and cellulose acetate and polyvinyl chloride were obtained in 1927 and polymethylmethacrylate in 1928 and urea-formaldehyde resins were obtained in 1929. These are polyethylene in 1932, nylon, polyacrylonitrile, styrene-acrylonitrile, and polyvinyl acetate in 1934, polyurethane in 1937, poly (tetrafluoroethylene), known as teflon in 1939, and polyacrylonitrile fiber, known as polyethylene terephthalate in 1941, and ortholon. followed.An important step in the development of plastics is to obtain reinforced plastics by mixing these materials with glass, graphite and carbon fibers. The mechanical properties of these materials reach the level of metals and plastics rival metals in many application areas.
