PEG-b-PCL copolymer: formulation and optimization by DOE; determination of Mn by multivariate regres
What is it about?
in this work, we couple NMR spectra with chemometrics for firstly time.
Why is it important?
NMR is not suitable for determination of Mn for high molar mass PEG–PCL copolymers. Thus, the information that can be derived from NMR spectra is restricted because of broad and overlapping signals, poor solubility of polymers or non-availability of suitable solvents. NMR coupled with partial least squares (PLS) regression is applied to determine the Mn of MePEC in the present study.
