Macromolecules Polymers
The current research on macromolecular polymerization is the key to chemistry. Macromolecular polymerizers, from the aggregation of small molecules to obtain a macromolecular structure. There are various methods of polymerization, such as addition polymerization and condensation polymerization.
During addition polymerization, small molecules have unsaturated bonds, which are introduced by initiators, and the bonds are opened and connected to each other to form macromolecular chains. There are no by-products of small molecules in this process. For example, ethylene is polyethylene, and its chain is flexible, with good flexibility and insulation. Films, pipes, etc. are often made.
Condensation polymerization is different. When small molecules react, in addition to forming macromolecular chains, small molecules such as water and alcohol are still separated. Like polyester, it is formed by condensation of dibasic acid and dibasic alcohol. Its molecules are regular and high in strength, and can be used to make fibers and engineering plastics.
Macromolecular polymers have special properties. Their molecular weight is large, the melting point and strength are higher than ordinary molecules. And they have plasticity and elasticity. Due to the weak interaction between chains, they can be deformed when heated, and they can be shaped when cold. This property makes them easy to process.
In view, macromolecular polymerization is the most important in the field of materials, providing a foundation for the development of various industries, promoting the production of new materials, and promoting the advancement of life and science and technology.
