Monomers and Polymers of Macromolecules
On monomers and polymers of macromolecules
Everything in the world has its own structure. In the field of chemistry, macromolecules have complex structures and unique functions. To understand the mystery of macromolecules, it is necessary to explore the relationship between their monomers and polymers.
Monomers are like the cornerstones of buildings, and are the basic units of macromolecules. Their structure is simple, but they have specific chemical activities and can interact with each other to form polymers. Monomers have their own characteristics, either single atoms or small molecules, which are connected by covalent bonds. For example, olefin monomers have unsaturated carbon-carbon double bonds, which are highly active and can initiate polymerization reactions. When the conditions are appropriate, the double bond is opened, and the monomers are attached end to end, like chain beads, gradually converging into a long chain of polymers.
polymers are the products of monomer polymerization. Many monomers are chemically arranged in an orderly manner to form giant molecules. According to the type of monomer and the polymerization method, the structure and properties of polymers also vary widely. Linear polymers, monomers are connected to form a linear long chain, which is flexible and malleable. For example, common polyethylene can be made into films and pipes, which are widely used. The body polymer, the monomers are cross-linked into a three-dimensional network structure, with a hard texture and high strength. Such as phenolic resins, it is often used as insulation and heat insulation materials.
Polymerization is the process of monomer polymerization into polymers, which is the key means of chemical synthesis. Addition polymerization, such as the above-mentioned polymerization of olefins, the double bonds of monomers are opened, and they are added to each other, without the formation of small molecule by-products. In condensation polymerization, when monomers react, in addition to forming the polymer backbone, small molecules such as water and alcohol are removed. Amino acids are condensed and polymerized to form proteins, during which the formation of peptide bonds is accompanied by the removal of water molecules.
The monomers and polymers of macromolecules are closely related and interdependent. The properties of monomers determine the basic characteristics of polymers; the polymerization method determines the structural morphology of polymers. In-depth research is of great significance in various fields such as materials science and biomedicine. Material research and development, monomers and polymerization pathways can be selected according to needs to produce polymer materials with specific properties. In biomedicine, the monomer and polymerization mechanism of biological macromolecules such as nucleic acids and proteins help to explore the mysteries of life and develop new drugs and therapeutic methods.
