Отмечена нестабильность содержания непредельных эфиров фталевой кислоты в исследуемом объекте с наиболее вероятным интервалом колебаний по йодному числу, в пределах от 24,4 до 44,4. Установлена прямая зависимость указанных пределов варьирования от содержания в кубовом остатке ректификации бутанола 2-этилгексен-3-ол-1 в количестве 9,0-17,5 % и 2-этилгексен-2-ол в количестве 35-43 %. Найдено соотношение непредельных эфиров 2-этилгексил-2-этилгексен-3-фталата и 2-этилгексил-2-этилгексен-2-фталата в непредельном пластификаторе - 1:2÷5. Показано, что при дефиците в производстве бромированного пластификатора с низким содержанием брома его необходимое количество можно получить разбавлением бромированного пластификатора с высоким содержанием брома. В качестве разбавителей предложены диоктилфталат и исследуемый непредельный пластификатор. Отмечено, что при неполном бромировании непредельной основы ненасыщенные эфиры не оказывает отрицательного влияния на качество композиций, делают бромсодержащую систему более реакционноспособной, что приводит к дополнительной сшивке молекул полимеров и повышению прочности композиции. Показано, что модификация непредельного пластификатора бромированием позволит получить тройной эффект ингибирования процесса горения за счет элиминирования бромистого водорода из бромированных эфиров, увеличения продолжительности его элиминирования и способности непредельных эфиров реагировать с активными радикалами, выделяющимися при термораспаде и горении полимерных композиций.</p></abstract><trans-abstract xml:lang="en"><p>The possibility of using unsaturated phthalates obtained by the esterification of phthalic anhydride with distillation residues of butyl alcohols as a basis for the synthesis of a bromine-containing plasticizer-fire retardant was evaluated. prene, polyvinyl chloride, and polyvinyl acetate. Instability of the content of unsaturated esters of phthalic acid in the test object was noted with the most probable range of fluctuations in iodine number, ranging from 24.4 to 44.4. A direct dependence of the indicated variation limits on the content of 2-ethylhexene-3-ol-1 in the distillation residue of butanol in the amount of 9.0-17.5% and 2-ethylhexen-2-ol in the amount of 35-43% was established. The ratio of unsaturated esters of 2-ethylhexyl-2-ethylhexene-3-phthalate and 2-ethylhexyl-2-ethylhexene-2-phthalate in an unsaturated plasticizer is 1: 2 ÷ 5. It has been shown that with a shortage in production of a brominated plasticizer with a low bromine content, its required amount can be obtained by diluting a brominated plasticizer with a high bromine content. Dioctyl phthalate and the investigated unsaturated plasticizer were proposed as diluents. It is noted that with incomplete bromination of an unsaturated base, unsaturated esters do not adversely affect the quality of the compositions, make the bromine-containing system more reactive, which leads to additional crosslinking of polymer molecules and an increase in the strength of the composition. It is shown that the modification of an unsaturated plasticizer by bromination will make it possible to obtain a triple effect of inhibition of the combustion process due to the elimination of hydrogen bromide from brominated ethers, an increase in the duration of its elimination and the ability of unsaturated ethers to react with active radicals released during thermal decomposition and combustion of polymer compositions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отходы производства</kwd><kwd>пластификаторы</kwd><kwd>модификация</kwd><kwd>антипирен</kwd></kwd-group><kwd-group xml:lang="en"><kwd>waste production</kwd><kwd>plasticizers</kwd><kwd>modification</kwd><kwd>flame retardant</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Леванова С.В., Красных Е.Л., Моисеева С.В., Сафронов С.П. и др.
