| Abstract: | IR spectroscopy showed that dipole-dipole interactions of the hydrogen bond type with formation of stereocomplexes take place
between macromolecules of the copolymer of ethylene with vinyl acetate (CEVA) and copolyamide (CPA) during fabrication of
blends. CEVA affects the network of intermolecular hydrogen bonds in CPA like a polar solvent: due to the reaction of the
carbonyl (C=O) group in CEVA with the amide groups in CPA, rearrangement of the network of hydrogen bonds in the polyamide
and formation of a new stereocomplex take place.
