The choice of the optimal methodology for the assessment of the molecular weight distribution of

polymethylene naphthalene sulfonates

he technical polymethylene naphthalene sulfonates (TPNS) are used in different industries. TPNS are thought to be mixture

of polymethylene naphthalene sulfonates with wide molecular weight distribution (MWD) parameters and different span

of the average molecular weights. MWD and average molecular weights determine the field of application of this product. For

evaluation of TPNS MWD characteristics, two chromatographic methods are used gel permeation (GP) and thin layer (TL)

chromatography as well as extraction-precipitation (EP) procedure. All these methods have drawbacks. For EP, the drawbacks

are the duration of analysis; low reproducibility and low selectivity of fractionating and; for GP and TL chromatography, the

drawbacks are the poor informativity because of the insufficient separation and complexity of the quantitative assessment of

obtained data. We believe that reversed phase high performance liquid chromatography (RP-HPLC) with spectrophotometric

detector is an interesting and advanced method. The systematic researches of TPNS MWD by means of this method are very

rare. The objective of this research is to develop the methodology of HPLC and to compare it with known methods of the

assessment of TPNS MWD. The capabilities and advantages of the methodology of HPLC are demonstrated on the TPNS

samples for different industries. The high reproducibility and informativity of the method are revealed compared to exist

methods. New method allows to separate, identify and quantify the full fraction makeup of TPNS. The characteristics of MWD

are estimated reliably.
