Question

The monomers used in addition polymerisation through free radical should be very pure because:

• A. the traces of impurities act like inhibitors resulting in short chain polymers
• B. the impurities result in formation of different products
• C. the polymer formed is impure
• D. catalyst does not function in presence of impurities

Answer 1

Answer: (A)

the traces of impurities act like inhibitors resulting in short chain polymers

Small amounts of impurities may combine with free radical polymerisation and thus, acts as inhibitors which slow down or even stop the polymerisation.

The correct option is [A].
