Investigation of Functional Carboxy-Containing Oligomers by IR and NMR Spectroscopy
New functional oligomers have been synthesized via intereaction of epoxy oligomers with carboxylic ones or with dibasic carboxy acids. In some cases synthesis was accompanied by ROP-polymerization of DGEBA, initiated by carboxylic oligomer. The structure of obtained products was investigated by IR, 1Н and 13C NMR spectroscopy.
