  • Method for determining a degree of polymerisation of a polymer
    Patent number: 11300518
    Abstract: A method for determining the degree of polymerization of a polymer is disclosed, the polymer being contained in a sample (2), the method comprising the following steps: a) illuminating the sample (2) using a laser beam (11) and acquiring (100) a Raman spectrum (S) representative of the polymer; b) identifying (110) a peak of interest (Pi) and determining (120) a position (vi) of the peak of interest in the Raman spectrum; c) on the basis of the position of the peak of interest, using a calibration function (ƒ) to determine a degree of polymerization (DP, DE) of the polymer, the calibration function expressing a variation in the position of the peak of interest as a function of the degree of polymerization of the polymer.

  • PREDICTIVE DETERMINATION OF EXCESS CHEMICAL POTENTIALS
    Publication number: 20210202046
    Abstract: Method for the predictive determination of an excess chemical potential including the following steps: a. performing a typology of the chemical species which are present in a solution, in order to determine at least one true species, b. associating a vector of physical magnitudes with each true species determined in step a c. performing an operation on at least one of said vectors of physical values in order to determine an excess chemical potential of an apparent species.
