I have tried the proton NMR of Dendritic PEI and have conjugated it to other polymer via amidation. So now I have to evaluate the conjugation degree using NMR.The software I use is NMR 1D.
How will we evaluate the conjugation degree in such a case and how to integrate the peaks of PEI to that of the polymer in the conjugated system.
I would really use some help if I could get it as I am struck in this for more than 10 days.
Thank you in advance
To evaluate the degree of conjugation of dendritic PEI to another polymer using NMR, identify and integrate the distinct peaks for both components in the spectrum, normalizing the integral values against a reference peak. Calculate the conjugation degree by determining the ratio of the integrated areas of PEI to the polymer, which reflects the extent of conjugation.
Abdelhak Maghchiche Thank you for th response.
I tried to do the same, but is struct where you would have to give the normalisation as the no for the protons in DPI. Since I couldnt find that, is it correct to give the SA referencce peak as 4 (no of protons in SA) and based on that, evalauate the conjugation degree with the integral of DPI?
