To improve physical and chemical, mechanical and adhesive properties of polymerizable compositions the directions of their modification were defined. A photosensitive composite material based on oligouretanacrylate aliphatic nature, oligoetheracrylate, photoinitiator system was developed. To increase the rate of coating curing the synthesis of oligomeric modifiers was conducted. The relationship between the kinetic parameters of photopolymerization and properties of the polymer coatings was determined, the directions of regulation of their functionality when interacting with different oligomeric modifiers to improve lightsensitivity and adhesion strength were defined. A pilot batch of photopolymer adhesive was produced with the next material testing at the manufacture.
