Polymer-polymer composites based on polyaniline and polymethacrylic acid were obtained. The electrical conductivity, heat resistance, X-ray spectra of the obtained composites were studied. Intermolecular hydrogen bonds are formed between the components of the composite. Increasing the content of polymethacrylic acid in the composite increases its heat resistance. The process of thermal destruction of polyaniline, polymethacrylic acid and composite is complex and takes place in several stages. The conducted quantum chemical calculations confirm the conclusion about the formation of intermolecular hydrogen bonds between the components of the composite. [ABSTRACT FROM AUTHOR]

Are obtained polymer-polymer composites based on polyaniline and water-soluble polymers - polyvinyl alcohol, polymethacrylic acid and copolymer of styrene with maleic anhydride. Investigation of thermomechanical properties and X-ray and FTIR spectra showed that intermolecular hydrogen bonds are formed between the conductive polymer and a water-soluble polymer. Constructed quantum-chemical models of composites were proposed. The energy of hydrogen bonds is found. [ABSTRACT FROM AUTHOR]
