A very simple derivation of a Fokker-I'lanck equation for the distribution function oP the cod-to-end distance of polymer chain is proposed. In contrast to well known methods of obtaining this equation the derivation also makes it possible to obtain the correct expression for the self-consistent fi
For the Schulz broad distributions with initial weight-polydispersity from 2 to 10, the correlation between the intrinsic viscosity and the degradation degree, DD = ln(M,,JM,,), has been found as the following equation system: ln[v] = 1n[qloa(ln Po -In P + DD); P = P F + (Po -P F ) X exp((So -1.43)(
A previously derived general equation, correlating the intrinsic viscosity of a polymer with -~'n, ~w and 2~,, is tested with experimental data. Its application for the calculation of average molecular weights is discussed. Good results have been obtained for the calculation of 2f/" z using experime
