Spectroturbidimetric titration

The molecular weight and compositional heterogeneity of 2M5 VP-AA copolymers having various molecular weights and composition have been studied by spectroturbidimetric titration [66]. The fractionation of copolymers in a mixture of methanol/toluene and methanol/diethyl ether leads to the precipitation... 

In particular, the ensemble of a new phase during phase separation proceeding in a multi-component system belongs to such systems. In this case, the turbidity spectrum method provides the determination of the mass-volume new-phase particle concentration, as well as the degree of phase transition this can be used to construct the molecular-mass polymer distribution function (the method of spectroturbidimetric titration for polymer solutions—subsection 3.2.3) and for a phase analysis (identification) of the pheise separation type in polymer. systems (paragraph 3.6.2.5, sections 6.2 and 6.4).

Spectroturbidimetric titration (STT) of polymer solutions improves the situation. It is a version of TT which enables one to solve correctly both the reverse problems at the cost of a slight complication of the experimental technique and the calciilatioiial procedure. SI T implies measuring turbidity at several wavelengths (not at one), i.e. recording a turbidity spectrum. 

Spectroturbidimetric titration (STT) of polymer solutions is a version of summative fractionation with optical weighing" of the polymer in the colloid-disperse state.
