Extended data:

1, the number of carbon atoms in the molecule of organic compounds decreases and the molecular weight decreases.

2. Macromolecules of polymer compounds are broken down into smaller molecules.

3. Plastic degradation: The term plastic degradation refers to the end of polymer life cycle. Plastic degradation is to reduce the molecular weight of polymer and the physical properties of polymer materials (plastics). Typical performance is: plastic is brittle, broken, soft and hard, and loses its mechanical strength.

4. Under the influence of external factors such as heat, light, mechanical force, chemical reagents and microorganisms. The polymer chain breaks randomly, and the side groups and low molecules are eliminated, which leads to the decrease of polymerization degree and relative molecular weight.
