Question

Select the incorrect statement from the following option.

(a) Condensation polymerisation requires two reactive functional groups to be present at both ends of the monomer

(b) No by-product is formed in condensation polymerisation

(c) In condensation polymerisation, growth of chain occurs at minimum of the two active centres

(d) In condensation polymerisation, polymer MW rises steadily throughout the reaction

The question was posed to me during an interview.

Asked question is from Polymerization in chapter Polymers of Engineering Chemistry I

Answer 1

Right answer is (b) No by-product is formed in condensation polymerisation

For explanation I would say: Generally a by-product is formed in condensation polymerisation. All the other options are correct.

Condensation polymerisation requires two reactive functional groups to be present at both ends of the monomer and growth of chain occurs at a minimum of the two active centres. In condensation polymerisation, polymer MW rises steadily throughout the reaction.
