The laws governing the destruction of polymer coatings during their use are partly defined by the fact that the rate and other specific features of their destruction are influenced by internal stresses occurring as a result of incomplete relaxation processes due to peculiarities of structure formation.1This paper deals with an investigation carried out with the help of the NMR method of higher resolution, electron microscopy and physicochemical methods to study the effect of the oligomeric block structure, length and flexibility of a number of oligoester acrylates on peculiarities of oligomer structure formation as well as coatings structure and properties and their durability in the conditions of aging under ultraviolet radiation. It's been shown that coatings set through the intermediacy of mesomorphic structure formation have increased durability of 2-2.5 times, during aging under ultraviolet light radiation. Of all the studied systems those with a globular structure tend to have the lowest durability.
