3) Suppose that Mn of poly(methyl methacrylate) was obtained as 300,000 Da in the absence of chain transfer agent by using 1 M methyl methacrylate. What would be the molecular weight of the poly(methyl methacrylate), if 0.01 M carbon tetrabromide is used as a chain transfer agent with Ct of 0.27 at the same reaction conditions? Assume that termination is only by disproportionation for poly(methyl methacrylate). (20 points)
