Hey Mate here is your answer...... ✔️✔️✔️

Plastics are made from natural materials such as cellulose, coal, natural gas, salt, crude oil through a polymerization aur poly condensation process. The production of plastic begins with distillation of crude oil in an oil refinery....... ✔️✔️✔️

Hope it will help you..... ☺️☺️☺️

Plastics are polymers, chains of simple organic chemicals (monomers), linked together in long chains. The monomers are synthesized in refineries, from oil. The linking of the monomers in the polymer chain is done inside polymerization .  Plastics are derived from organic products. The materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds. To become useful, it must be processed.

Prepare raw materials and monomers

2.Carry out polymerization reactions

3.Process the polymers into final polymer resins

4.Produce finished Ethylene and propylene, for example, come from crude oil, which contains the hydrocarbons that make up the monomers.

The hydrocarbon raw materials are obtained from the "cracking process" used in refining oil and natural gas (see How Oil Refining Works).

Once various hydrocarbons are obtained from cracking, they are chemically processed to make hydrocarbon monomers and other carbon monomers (like styrene, vinyl chloride, acrylonitrile) used in plastics.
