A 2.0 M solution of styrene in ethylene dichloride is polymerized at 25°C 

using 4.0 x 104 M sulfuric acid. 

a) Calculate the degree of polymerization if full monomer conversion is obtained. 

b) We want to reduce the molecular weight of the polymer by the addition of transfer agent Can you give an example of transfer agent for this polymerization? [You can data from the literature] 

What would be the degree of polymerization if the monomer solution contains isopropylbenzene at a concentration of 8.0 x 10 M? Explain the mechanism using schematic representation.
