Апстракт:
The paper investigates the effects of adding methyl methacrylate (MMA) on the properties of synthesized acrylate emulsions. The samples were synthesized in batches with the addition of MMA ranging from 10 to 50 % of the total mass of butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA). Fourier transformation infrared (FTIR) spectroscopy was used to analyze the molecular structure of synthesized acrylate emulsions and the results confirmed that a quantitative polymerization reaction occurred. The analysis of thermal properties showed that the addition of methyl methacrylate increases the glass transition temperature of the films obtained by drying the synthesized emulsions. The tensile strength and elongation at break increased proportionally with the increase of the content of MMA in the synthesized emulsion samples. Since the obtained acrylate materials can be used to improve the water impermeability of paper and other materials, the experiment involved applying the emulsions (in a thin layer) on a sheet of paper and investigating the resistance of the paper to water and oil. The results showed that all emulsions were impermeable both to water and oil.
