First things it is not Polythene it is Polyethylene.
Poly = many, mer = unit, Polymer = Many units,
Mono = single or One, Monomer = single unit,
Polyethylene = Polymer.
Ethylene = Monomer, So Monomer of Polyethylene is ethylene.
Ex, Monomer of Polypropylene is Propylene.

Polythene polymer form by addition polymerization reaction. In the formation polythene polymer repeated addition of unsaturated ethylene monomer takes place.
Reaction of formation of polythene polymer is n Ch2 = Ch2+\'(-Ch2-Ch2-)n ethylene, poly-ethylene.
Reaction of formation of polythene polymer is n Ch2 = Ch2+\'(-Ch2-Ch2-)n ethylene, poly-ethylene.

Yes @Bikash is right.
Polymerization process is different depends of catalyst, temperature. Process involve initiation, propagation and termination. Based on that we got LDPE, HDPE, LLDPE, UHMWPE etc.

Ethylene is the Monomer. The reaction is in the following way.
Polymerization.
CH2=CH2 ------------------> (--CH2-CH2--)n
Monomer Polymer.
Polymerization.
CH2=CH2 ------------------> (--CH2-CH2--)n
Monomer Polymer.

When monomers is repeated then forms polymers.
When -n (CH2=CH2) ->>>>>>>> (CH2=CH2) n is called polyethyline.
When -n (CH2=CH2) ->>>>>>>> (CH2=CH2) n is called polyethyline.

Because Polymers are formed from joining together of monomers. Therefore, many molecules of ethylene will form polythene.

As we know polymer is double bond because monomer + monomer is called polymerization.

No.of monomers are called polymers. So ethylene monomers are called polythene.

Polythene is said to be co polymer because similar molecule is ethylene.

(-CH2=CH2-)n --> (-CH2-CH2-)n
Ethylene --> Polythene
Ethylene --> Polythene
