Question

a.) In what basic way is emulsion polymerization similar to suspension polymerization?

b.) What advantage does this give over solution polymerization?

c.) In what way do emulsion and suspension polymerization differ basically?

d.) In an unstirred, bulk polymerization that proceeds to 100% conversion, how can the effects of shrinkage and heat of polymerization be handled?

Answer 1

a) in both external agent had to be added in suspension stabilizing agent and in emulsion surfactant.

b)high weight polymer

In solution problem of chain transfer ruleout here there is no such problem

c) suspension is mechanical process where stablizing agent is added

In emulsion is chemical process where surfactant is added

Suspension monomer insoluble

Emulsion monomer email is soluble in aqueous phase.

d)heat problem can be solved by providing jacketing around the vessel and pass the liquid in jacket according to requirement.i.e if temperature is high enough then cold if it's less then hot if desire.
