The a value is higher than calculated in this work, because these calculations were performed with number average molecular weight (Mn) which rearranges the value of a and forces him to enter into unbranched or linear molecules (a > 0.5), on the other hand, if molecular weights (Mw) ware used to value would be less than 0.5. GYA primarily conducted research. By studying the molecular weights of various solutions of polymer, Solomon-Ciuta arrived at the formula which allowed the calculation of the intrinsic viscosity of polymer solutions by a single viscosity determination. All possible degrees of curling can be displayed by any molecule, but there will be an average configuration which will depend on the solvent. In a good solvent, which shows a zero or negative heat of mixing with the polymer, the molecule is less-extended, and the intrinsic viscosity is high.
