聚合物与日常生活（Polymers and daily life） Hongkong Chemical Society literacy competition Polymer and daily life (excerpt) When the builders put two bricks together, plus the appropriate movable soil, the two bricks will be firmly joined together. By analogy, when the worker added the last brick, a huge, huge wall was built, and the giants of the polymer, the molecule, were created by a similar principle. The polymer dot polymer is made up of the two words Poly and Meros in Greek. They represent many and partial. The polymer is a large molecule consists of a large number of single or multiple simpler structure units, these units on both the right and left with a chemical bond, can be combined with each other to form a long chain like polymer. In simple terms, polymers can be divided into two broad categories, natural polymers and synthetic polymers. Some polymers, such as starches and proteins we know, are naturally occurring and are known as natural polymers. All life on earth, and even you and me, is simply made up of these polymers. In addition to these natural polymers, human beings have been able to produce polymers by artificial methods in the recent century, so we call them artificial polymers. Poly complexes, this part and filled with a lot of strange things in our daily life is a very important part of the assessment, in daily life, it is not difficult to find some articles composed of polymer. In fact, including clothing, food, shelter, and polymers have very close relationship with the US, in addition to metals and inorganic compounds, almost any material with polymer polymer properties, the following let us into the world to explore the relationship between polymer polymer in our underwear, food, shelter, and more the. In clothes, we can not fail to mention the widely used polymer nylon?. Before the birth of nylon, the main material of human clothing was only some natural silk. In the recent century, the invention of nylon has gradually replaced silk as an indisp
