The characteristics of high molecular polymer

The characteristics of high molecular polymer

1. High molecular weight polymer is a long-chain molecule composed of a large number of repeating units, with a relatively large molecular weight, usually between one thousand and one million.

2. Polymers have high flexibility and mobility of molecular chains, because they can be twisted and stretched freely, so that they can adapt to different environments and stresses.

3. High molecular polymers are usually amorphous or semi-crystalline, because the structure of molecular chains is irregular and it is difficult to form orderly crystals.

4. High molecular polymers usually have good chemical stability and physical stability, and can withstand the influence of different chemical and physical environments.

5. High-molecular polymers usually have high mechanical strength and toughness, because long-chain molecules make the polymer form an interlaced network structure, which can absorb the impact of external forces.

6. High molecular polymers can have different physical and chemical properties, such as thermal stability, electrical insulation, transparency, softness, air permeability and water absorption, etc.
