Question

name the molecules which are used for making plastics ​

Answer 1

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.

Answer 2

Answer:

Polyethylene. Ethylene is a simple molecule composed of two double-bonded carbon atoms and four hydrogen atoms. At room temperature it is a gas. Ethylene molecules can be chemically bonded, end-to-end, to form a chain or polymer called polyethylene.
