Spectroturbidimetric titration of polymer solutions as a method for analytical fractionation

Spectroturbidimetric titration of polymer solutions as a method for analytical fractionation [Pg.316]

Accumulating fractionation is one of the ways of polymer fractionation, where addition of a new portion of the precipitant is followed by determination of the total amount of the precipitate without removal of the precipitated fractions (Battista, 1967). [Pg.316]

As a matter of fact, the degree of phase conversion is determined at different stages of fractionation. [Pg.317]

the ideas of the method are simple and attractive, but their realization is not as simple as that. [Pg.317]

Application of TT to evaluate. MWD means to correctly solve two reverse problems. The first, optical problem consists in calculating a precipitation curve x - x( j) from the meausiired properties of scattered light the second, thermodynamic problem must provide a means of converting this curve x - 2(7) into the corresponding. VfWD function (7 is the volume fraction of precipitant in the system). [Pg.317]
