“…At the same time, in the entire studied wavelength range of irradiation, the intensity of short-wave emission remains higher than the intensity of long-wave. As it was established [21], the stiffness, strength of the polymer and the modulus of elasticity in the considered series are greatest in the polymer with the shortest oligomeric block, i.e. in OCM 1.…”

The luminescent properties of photocured aliphatic and aromatic network polycarbonate methacrylates containing organic fluorescent dyad have been studied. The dyad molecule includes two photosensitive fragments – tetraarylimidazole with a hydroxy group and azomethinocoumarin, in each of which excited state intramolecular proton transfer occurs, which leads to the appearance of two emissions - blue and green. It was established that the ratio of the intensities of these emissions depends on the excitation wavelength, as well as on the length, flexibility and polarity of the matrix oligomeric bridges.

“…In the polymer matrices with the longest flexible oligomeric bridge, OCM-2/1, the imidazole luminescence band predominates again. This is probably due to the intermolecular interaction of long oligomeric blocks in network polymers, leading to the formation of associates capable of tightening the polymer, as described in [24]. From the data obtained for the studied aliphatic polycarbonate methacrylates, it can be seen that OCM-2 is the most suitable for the observation of double fluorescence.…”

The luminescent properties of photocured aliphatic and aromatic network polycarbonate methacrylates, containing organic fluorescent dyad, have been studied. The dyad molecule includes two photosensitive fragments—tetraarylimidazole with a hydroxyl group and azomethinocoumarin—in each of which excited state intramolecular proton transfer (ESIPT) occurs, leading to the appearance of two emissions: blue (450 nm) and green (535 nm). It was established that the ratio of the intensities of these emissions depends very significantly on the excitation wavelength, as well as on the length, flexibility and polarity of the matrix oligomeric bridges.

“…В работах [1][2][3] для анализа причин разрушения лакокрасочных покрытий фасадов зданий использовалась диаграмма Парето, т. е. выделились в первую очередь приоритетные факторы, которые попадают в 80 % куммулятивной кривой. Авторами установлено, что список видов разрушений покрытий, составляющих 80 % куммулятивной кривой, состоит в основном из растрескивания и отслаивания покрытий [4], однако нередко наблюдается одновременно три типа разрушения: когезионный (растрескивание), адгезионный (отслаивание) и смешанный [5][6][7][8][9][10].…”

The paper investigates the probability of cracking for polyvinyl acetate-cement coatings depending on their thickness and strength of adhesion to the cement substrate. Data on changes in the cohesive strength of paint coatings depending on their thickness is provided. A model is proposed for changing the cohesive strength of the coating depending on the thickness. A statistical assessment of the probability of destruction is conducted to examine cracking. A graphical model of the probability of cohesive failure depending on the thickness and adhesion strength of coatings is proposed.
