In case of condensation of polymers (J&K CET 2008)
A.high molecular weight polymers are formed all at
B.lower molecular weight polymers are formed all at
C.molecular weight of polymer rises throughout the✓ Correct
D.have no specific relation to their molecular weight
Explanation
The process of condensation polymerisation takes place in the following manner : Condensation Monomers Dimer → A B A B Condensation → A B A A B A → A B A B A B A B In this process, no initiator is required, and it is also called step growth polymerisation. Thus, the molecular weight of the polymerises throughout the reaction.
