The analysis of structure and composition of polymers with oleic and palmitinic acids’ molecular imprints

Abstract

Polymers, based on imidizated polyamide acid and also on polyimides RD and DFO with
molecular imprints of oleic and palmitic acids, were analyzed with methods of IK-spectroscopy and
electronic microscopy. Established that polymers’ saturation of fat acid changes the type of spectrum.
Subsequent model’s removal with help of solvent brings to appearance of molecular imprints – cavities,
which are complementary with the model in size, shape and arrangement of functional groups. With
methods of electronic spectroscopy is stated that elemental composition of etalon polymers agrees closely
with polymers with molecular imprints after repeated extraction of butanol and water.
