Big%20smileHi all
 
Right now I am working on ATRP, but I faced a problem, I was trying to polymerise N-substituted styrene with MBP(Methyl-2-bromo propionate) as initiator,CuBr-PMDETA( Cat/ligand), anisole(solvent) in the ratio of
M:I:Cat:Ligand= 100:1:1:3. The problem is that even if I run the reaction for 24 hrs the mol weight is too low and I think the end bromo group is missing as I am not getting any signal for the bromo end group in NMR.
What should be done?
