In the article, the basic physical and chemical properties of polymers based on glyphthalic resin are considered. The main advantages and disadvantages are revealed. The areas of application and the main methods for obtaining glyphthalic resins are considered. The research on studying the course of the polycondensation process on the change of acid number during the reaction of obtaining glyphthalic resin of polyatomic alcohol of glycerol and phthalic acid anhydride is carried out. It is revealed that the results of acid number determination during polycondensation can be used for directed regulation of synthesis of alkyd oligomers and their subsequent curing to obtain a polymer with specified properties. The data was obtained that the polymer under study can be further modified to give special properties that extend the area of its application, as well as to ensure the environmental safety of the waste generated during its use. On the basis of the available data, it is concluded that further research of glyphthalic resin is necessary.
Key words: glyptal resin / glycerin / phthalic anhydride / acid number
