Emulsifiers are molecules that have two different ends. A hydrollic end water loving that forms chemical bonds with water but not oil. A hydrophobic end water hating that forms a chemical bonds with oils but not oil.
it is the fusing together of monomers and hydrocarbons by using heat.addition to above answere.it is the addition of monomer molecules to form bigger particle which is called polymer.the reaction is carried out by heat, and catalyst like potassium per sulphate,cumene peroxide,s.m.b.s.etc.as well as emusifier is must for emulsion polymerisation.the molecular wt. of polymer is much more than monomer.
