Polymer communicationThermal blob size as determined by the intrinsic viscosity
چکیده انگلیسی

It is shown that the mass of the thermal blob, normalized by the mass of its effective monomer, is a unique function of the solvent quality represented by the Mark-Houwink-Sakurada exponent. This function specifies the relation between intrinsic viscosity and that measured in a theta solvent. As a result, the Mark-Houwink-Sakurada exponent can be determined from intrinsic viscosities measured for a single molecular mass. The form of the derived function is also confirmed by the constancy of calculated thermal blob mass for a given polymer of different molecular masses, dissolved in a solvent of a given quality.
