Definition Macromolecule Polymer
Between heaven and earth, all things metamorphose, and there is a type of substance with a complex structure and a large volume, which is called a macromolecular polymer. Macromolecular polymers are made of many small molecule monomers, which are connected and polymerized with each other in a specific bonding way.
The method of monomer polymerization is either addition polymerization, where the double bonds of small molecules are opened and connected to each other to form a long linear chain, which is like a string of beads; or condensation polymerization, small molecules are removed from the monomers, and the rest are connected. During the polymerization process, small molecules escape and macromolecules gradually form.
Macromolecular polymers have specific properties. The length of their molecular chains and the complexity of their structures give them unique physical and chemical properties. Or tough as iron, can make equipment, strong load-bearing capacity and not easy to damage; or flexible like silk, can weave fabrics, soft to the touch and can be shaped. Its application is wide, in clothing, food, housing and transportation, everywhere. Clothing is made of synthetic fibers, which keep warm and breathable, and have a stable shape; food packaging materials, which preserve food, prevent bacteria and moisture; living building materials, which are strong and beautiful, and durable; running tires, which are wear-resistant and pressure-resistant to ensure safety.
Looking at nature, although there are natural macromolecules, such as starch, cellulose, protein, etc., synthetic macromolecular polymers can better meet people's needs and produce materials with different characteristics. Humans use chemical methods to explore the secrets of polymerization, create macromolecular polymers with wisdom and skills, add luster to life, promote technology, and open up a new world in the material world.
