The Micro-environment of Propagating Radical for Styrene in Bulk Polymerization

According to J. H. Freed, the dependence of line-width on the motion of β protons having a continuous distribution angle of conformation can be obtained by using a hindered oscillation model, that is T-12=γ2eB2βkT/2ω40I[kT/ω20I sum from n=ijcos(2θie)cos(2θje)mimj+sum from n=ijsin(2θie)sin(2θje)·mimj...
