In the first, we had to make the solution definitely. Put the water, initiator, monomer(styrene) and also surfactant into the flas

Improving conversion and so reducing the amount of ethylbenzene that must be separated is the chief impetus for researching alternative routes to styrene. Other than the POSM process, none of these routes li
