Crosslinking Agents

The influence of crosslinking agents on the characteristics and properties of films from aqueous dispersions of styrene-acrylic polymers Lacritex 309, 430 and 640 was studied in order to obtain coatings on textile materials. Mono-, di- and triglycidyl esters are chosen as crosslinking agents. The choice of aqueous dispersions of polymers and crosslinkers is due to strict environmental requirements for textile products. By determining the amount of aceton-insoluble fractions of the formed polymer films, it was determined that the incorporation of crosslinkers is required in the Lacritex dispersion 640, and the films based on Lacritex 430 and 309 are distinguished by a high degree of intermolecular crosslinking. Optimum concentrations of crosslinkers have been established, which provide a high degree of curing of Lacritex 640. Using the sol-gel method, the structural parameters of the spatial nets of styrene-acrylic polymers (the part of sol fraction, the degree of crosslinking, the part of active chains, the average molecular weight of the chain segment, the crosslink density) were calculated. The polymer films from the individual polymer Lacritex 430 have the highest indexes of physic mechanical characteristics. Lacritex 640/Laproxide 703 compositions can be used as polymer matrixes for textile materials. The formation of crosslinks of hydroxyl and carboxyl groups of the styrene-acrylic polymer with epoxy groups of the crosslinking agent was confirmed by IR spectroscopy. The investigation of the effect of water and soap-soda treatments at various temperatures shows that the films under study have high resistance to water and soap-soda solution. The results of investigation of the tensile strength, the elongation at break, the hardness of the coating surface by the Koenig method and the stickiness according to the FINAT method (Test Method Number 9) of the formed polymer films indicate high physical and mechanical properties such as increased mechanical strength and elasticity, reduced hardness and tackiness. Thus, based on the studies carried out, it can be concluded that the individual styrene-acrylic Lacritex polymers 309 and 430 provide the formation of a strong three-dimensional spatial structure of the polymer film and can be used without crosslinking agents. The use of Lacritex 640 is possible in the composition together with the Laproxide 703 crosslinking agent at an optimum concentration of 4%. A polymer film based on this composition has a high degree of crosslinking, and as a result, increased resistance to organic solvents, reduced hydrolytic degradation at high temperatures, and increased physico-mechanical properties. A polymer film based on this composition has a high degree of crosslinking, hence, has increased resistance to organic solvents, reduced hydrolytic degradation at high temperatures, and increased physical and mechanical properties. Forcitation:Slepchuk I., Semeshko O.Ya., Asaulyuk T.S., Saribekova Yu.G.
