A monomer undergoes addition polymerisation. A 1 mol sample of the monomer is completely

polymerised.

How many moles of polymer might, theoretically, be formed?

a) 1

b) 10-6

c) 1 divided by 6.02 into 10∧23

Answer is b and c, how?

Polymerization is where single molecules react with themselves and form a chain, a branch or a combination of both. There are repeated unites within the resulted polymer. This is the reactant (single molecule or monomer). As a result, the number of polymer is always less than the number of the monomer. Therefore, 1 mole of monomer, under complete polymerization, always forms less than 1 mole of polymer. Answer is b and c.
