Abstract: front page image
(EN)A method of obtaining copolymers of butylacrylate and of 1-((Alpha)alkylacrylate)-1-tertiobutylperoxyethanes consists in emulsion copolymerization of butylacrylate and of 1-((Alpha)-alkylacrylate)-1-tertiobutylperoxyethanes in the presence of an initiating system consisting of 0.008 to 1.640 per cent, to the total mass, of monomers of metabisulphite and of 0.002 to 0.360 per cent, to the total mass, of the combinations of a general formula NaxHySzO3, where x-integers 1 or 2, y-zero, z-integers 1 or 2. Depending on characteristics required: the swelling degree of the final product and the content of gel fraction therein, the quantity of the initiating system is determined by a formula: log C = (log((Alpha)-800) - log 2300) / 0,26 or log C = - (log(G + 200) - log 260) / 0,04 where C- the quantity of the initiating system expressed in percentage of the total mass of initial monomers; (Alpha)- the swelling degree of the final product expressed in percentage of the total mass of it; G-the content of gel fraction in the final product expressed in percentage of the total mass thereof.
(FR)Procede d"obtention des copolymeres de butylacrylate et de 1-((Alpha)-alkylacrylate)-1-tertiobutylperoxyethanes consistant a copolymeriser par emulsion du butylacrylate et 1-((Alpha)-alkylacrylate)-1-tertiobutylperoxyethane en presence d"un systeme initiateur comprenant entre 0,008 et 1,640 pour cent de la masse totale de monomeres de metabisulfite et entre 0,002 et 0,360 pour cent de la masse totale des combinaisons de formule generale NaxHyFzO3, ou X est le nombre entier 1 ou 2, Y est 0, Z est le nombre entier 1 ou 2. Selon les caracteristiques requises - le degre de gonflement du produit final et sa teneur en fraction de colloides -, la quantite du systeme initiateur est determinee par la formule: log C = (log((Alpha)-800) - log 2300) / 0,26 ou log C = - (log(G + 200) - log 260) / 0,04 C est la quantite du systeme initiateur exprimee en pourcentage de la masse totale des monomeres initiaux; (Alpha) est le degre de gonflement du produit final exprime en pourcentage de sa masse totale; G est la teneur en fraction de colloides dans le produit final exprimee en pourcentage de sa masse totale.
