Synthesis and Application of Latex-Based Ethylene-Propylene Copolymer on Methacrylic Acid

Abstract

The latex synthesis in the presence of ethylene-propylene copolymer and methacrylic acid (MAA) was considered for this experiment. The kinetic regularities of the synthesis process were determined and the optimal quantities and ratios of the components were determined both experimentally and by mathematical modeling. It was determined that a modified latex with optimal values ​​is obtained when the amount of methacrylic acid in the latex is 5 parts by weight. The absorbent composition was prepared latex-based based on synthesized EPC – + methacrylic acid. The prepared absorbent was impregnated with viscose (22B) and 222K kapron cord and a rubber-cord bond were determined. The findings of the present study show that the aqueous dispersions of EPC latex were synthesized using various emulsifiers with high technological stability. The presence of the main factors affecting the stability and adhesive properties of the EPC aqueous dispersion has been established. It has been shown that the best stability for 6 months is achieved at a pH value of 12.EPC water emulsion was modified in the presence of MAA by graft copolymerization.
