Background. Production of polymeric materials is one of the priority directions of development of Uzbekistan industry. One of such perspective materials may be random copolymers of methyl acrylate (MA) and Acrylic acid (AA). The synthesis of copolymers in a wide range of compositions allows obtaining materials with controlled hydrophilic and hydrophobic properties, which can be useful for practical application in the restoration and conservation of archaeological sites. Purpose. Synthesis of statistical copolymers of MA and AA in a wide range of compositions. Investigation of copolymers Solubility in solvents of different nature. Methodology. The synthesis of copolymers was carried out using a binary radical copolymerization. To prove the fact of copolymer formation, the results of functional group analysis and IR spectroscopy were used. The intrinsic viscosity of copolymers in different solvents was also investigated. Originality. Copolymers MA and AA are synthesized. It was found that varying the synthesis conditions can be obtained copolymers of different composition, significantly different in their hydrophilic and hydrophobic properties. Findings. The influence of the content of monomers in the initial monomer mixture of the composition of the copolymer have been studied. Copolymerization constants are determined. It is shown that depending on the composition of the copolymer samples have different solubility in water and organic solvents. Highlights: - synthesis of MA and AA copolymers has been carried out; - structure of copolymers has been investigated; - copolymerization constants have been calculated.
