How to determine accurately the radius of gyration of PEO with Molecular weight 4*10^6 (Polyethylene oxide)?

I want to estimate the radius of gyration Rg of PEO polymer with Mw 4*10^6 a.m.u. and also the overlapping concentration c*, according to Rg=N^(3/5)*a, where a is the length of a monomer and N is...
