Since the 19th century, humans have used modified natural polymer materials. Cremated rubber and nitrocellulose plastic (celluloid) are two typical examples. After entering the twentieth century, polymer materials have entered a stage of great development. First, in 1907, LeoBakeland invented phenolic plastics. In 1920 Hermann Staudinger proposed the concept of polymers and created the word Makromolekule. At the end of the 1920s, polyvinyl chloride began to be used on a large scale. In the early 1930s, polystyrene began mass production. At the end of the 1930s, nylon began production. After the great development of the twentieth century, polymer materials have had an important impact on the face of the whole world. Time magazine believes that plastic is the most important invention of humans in the twentieth century. Polymer materials also have an important impact on the cultural field and the way people live.
A polymer door is a door made of a polymer material. A polymer material is a material composed of a compound having a relatively high molecular weight. Many of the natural materials we come into contact with are usually composed of polymer materials such as natural rubber, cotton, and human organs. The same is true for synthetic chemical fibers, plastics and rubber. Generally speaking, a polymer that has been widely used in life and has been formed into an industrialized production scale is a general-purpose polymer material, and is called a functional polymer having a special purpose and function.
Polymer is the form of life. All living things can be seen as a collection of polymers.
Natural polymer materials such as branches, hides, and straw are the first materials used by human or human-like ancient intelligent organisms. In the long river of history, paper, gum, silk and other products processed from natural polymers have been intertwined with the development of human civilization.
