Abstract. The article presents the research results of synthesizing weakly acidic polycondensation type catio-nites based on naphthalene homologs isolated from local raw materials and studying their structure using various physicochemical analysis methods. Pyrolysis oil, a secondary product of the pyrolysis process of JV "Uz-Kor Gas Chemical" LLC, was selected for the research, and naphthalene homologs were separated from its composition by fractionation and used as raw materials in further work. During the polycondensation of naphthalene carbonic acid with formalin, polymethylene naphthalene carbonic acid was obtained in the process of obtaining a weak cationic, and its composition was compared using SEM (scanning electron microscope), IR-spectrum, TG (thermogravimetry) and DTA (differential thermal analysis).
