I would like to know if the amino function (N-H) of polypyrrole is chemically inert when synthesizing a mixture based on polypyrrole with a thermoplastic polymer characterized by the presence of a carbonyl function in acid media ?.
Dear Zeggagh Khaled, no it is not inert, it is the side for PPy functinalization derivatives. There exist some acid catalyzed reactions on N-H site. Please check the attached file. My Regards
Dear Abdelkader BOUAZIZ , Thank you sir for your answer but is the reactivity of the function (N-H) of the pyrrole with the carbonyl function of the small molecules the same as the polymers (large molecules) ? because I made the synthesis of the polypyrrole in situ with a polymer which contains a carbonyl function in an acid medium and according to the FTIR analysis I note the disappearance of the peak of carbonyl how to explain that? ....
Dear Zeggagh Khaled, what do you mean by 'carbonyl function'? Many functional groups have such a group. So you should specify the whole functional group having C=O. Generally speaking, the reactivity decreases because the diffusion limitations and the geometrical arrengements of the chain. You said the C=O band disapeared, what about the N-H one ? My Regards
Dear Abdelkader BOUAZIZ.only one carbonyl function (c=o) carried by the side groups of the polymeric units. on the other hand the bung (N-H) of the polypyrrole is invisible in FTIR because of the oxidation process (oxidation of the amine function); therefore I have nothing to say on this function.
