Addition Polymers -

Formed by repeated addition of monomers having double or triple bonds.

- wherein

Eg:- Polythene (from ethene), Polypropylene (from propane)

 

 

 

Free radical mechanism of Chain growth Polymerisation -

1.  Chain initiation step

  - Production of free radical

  - Addition of this radical to a monomer to produce chain initiating species

2. Chain propagating step

  - Formation of another big radical in each repeating step result in growth of polymer

3. Chain termination step 

  - At some stage when two radicals combine, pairing their unpaired electrons and forming a covalent bond.

 

- wherein

 

 

 

 

Given structure is a polymer of the monomer Isobutylene

the monomer is  Isobutylene.

 

 


Option 1)

Polyisobutane 

Option 2)

Polytert - butylene

Option 3)

Polysioprene

Option 4)

Polyisobutylene
