Chain growth
The automatic growth of monomers into polymers under the right conditions

Chain growth
Cain growth initiation
One reaction activates a monomer, usually creating a radical

chain Growth Initiation
Chain growth propigation
an active polymer compund reacts with an inactive monomer, addin it onto the end and activating it.

How to controll branching in chain growth
reduce branching by reducing pressure, temperature, and using a catalyst.

Burning Thermoplastics
the polymers break back down into moonomers, often rising to the atmosphere

Organic decomposition of plastics
organisms can decompose certain reactive groups, such as Ketones. Compounds longer than ~30 units will not break down
