Hi Shala
If you want to estimate with Bromin, your Monomer needed to be unsaturated so you can measure the excess of non-reaced bromin equivalent to the number of free bonds / monomer.

I think the practical setup does not differ so much from the regular bromin titration, maybe your stirring needs to be more intense or you add some solvent transmitters.
An excat protocoll is listed here:

good luck
Miss Shahla... First you need to break the emulsion to ensure the separation of the polymerized fraction. Once you remove the polymer from the emulsion, the determination may start with the bromine titration method provided that the monomer contains double bonds. The remaining steps was best mentioned by Frank above. Good luck...
