Calculations of the intrinsic constant of an ideal polymer from spectrophotometry data using factor analysis

A new procedure for the mathematical processing of the data of spectrophotometric titration using factor analysis was considered. Both the intrinsic constant of an ideal polymer and the concentration profiles of spectral forms in equilibrium can be calculated by the proposed procedure. Examples of spectrophotometric titrations of ideal polymers that simulate the behavior of polyuridine acid and differ in the number of monomer links in the polymer chain were considered. It was shown that the results of calculations using the proposed procedure are theoretical values of the intrinsic constant in the case when the system possesses high selectivity. In the case of insufficient selectivity, the agreement between the calculated and actual constants can be improved using normalization.
