Выражение встречается в следующем контексте: MW MW = Molecular weight
DP = _________________ DP = Degree of polymerisation
(162 + 80 x DS) DS = Degree of substitution

162 = Molecular weight of an un-substituted anhydro-glucose unit
80 = Molecular weight of the sodium carboxy methyl group

Both DP and MW are average values. Products with the same values could present a different distribution of molecular weight or DP

Different MW and DP distributions give different rheological properties
