Synthesis of alkyd oligomers based on bicyclo[2,2,2] oct-5-ene-2,3-dicarboxylic acid anhydride and its application for obtaining lacquer coatings

Abstract

The results of studies on the synthesis of modified by oil alkyd resin with the use of bicyclo [2,2,2] oct5-ene-2,3-dicarboxylic acid anhydride as acylation agent in the polycondensation reaction with polyols for obtaining lacquer coatings and the study of their operational properties are presented in this article. It is found that the chemical modification of alkyd resin by replacing phthalic anhydride on bicyclic dicarboxylic acid anhydride allows to increase hardness, strength, adhesion of coatings formed on steel substrates.
