tabul methacrylate was polymerized at a mass concentration of 200 g dm in toluene usine hisisobutyronitrile as initiator at a mass concentration of 1.64x 10-2 g dm and a reaction nnerature of 60 C. Calculate the initial rate of polymerization and the molar mass of the polymethyl methacrylate) formed in the initial stages of the reaction given that the relevant rate coefficients at 60 C are: Initiator dissociation, k=8.5x 10-6 s-1 Propagation, k, =833 dm3 mol- s- Termination, k, =9.3 x 10 dm mol- s- Transfer to monomer, kM=3.93 x 10-3 dm mol-1s- Transfer to solvent, k,=7.34 x 10-3 dm mol- s- Assume that the initiator efficiency f=0.7, that termination by combination is negligible, and that the density of the initial solution of MMA in toluene is 860 g dm. %3D %3D uitiator dissociation.
