Suspension polymerisation differs from emulsion polymerisation in producing

  • A.a solid block requiring to be broken up
  • B.beads rather than a fine latex
  • C.a fine latex rather than beads
  • D.a solution of polymer in solvent

Answer: B

Monomer droplets held apart by a mechanical stabiliser each polymerise as a small bulk reaction, giving pearls easily separated by filtration. No surfactant contaminates the product, which is why the route suits moulding grades.
