Question

how plastic AER formed ​

Answer 1

Answer:

How plastics are made :: PlasticsEurope Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. ... In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains.

Answer 2

Explanation:

Two main processes are used to produce plastics - polymerisation and polycondensation - and they both require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains. Each polymer has its own properties, structure and size depending on the various types of basic monomers used.
