What are the differences between solution and bulk and emulsion and suspension polymerization?

Emulsion Polymerisation Gives High Yield But It is of impure in nature And Emulsion Is Used For Polymerising Latex Based Monomer Where As Bulk Gives Us Pure Yield without Impurities ......

Solution Polymerisation Gives The Yield In Solution Form ......

Suspension Gives Yiels In Beads Form.....
