Description
Изобретение относитс к синтезу нолимеров на основе замещенных фенолов.This invention relates to the synthesis of substituted phenol based polymers.
Полифениленоксид (ноли - 2,6 - диметил-1,4фениленоксид ), относ щийс к полифениленовым эфирам, вл етс термопластом с высокими механическими, электрическими и тепловыми характеристиками. Особенно важна его термостойкость. Издели из полифениленоксидов хорошо работают в широком диапазоне температур (-200-190°С) без изменени диэлектрических свойств и формы, устойчивы к агрессивным средам, пару, жесткому излучению и грибкам. Указанные свойства определ ют области использовани полимера, особенно в электро- и радиотехнике, в химической промышленности и медицине.Polyphenylene oxide (nol-2,6-dimethyl-1,4-phenylene oxide), related to polyphenylene ethers, is a thermoplastic with high mechanical, electrical and thermal characteristics. Especially important is its heat resistance. Polyphenylene oxide products work well in a wide range of temperatures (-200-190 ° C) without changing the dielectric properties and shape, resistant to aggressive media, steam, hard radiation and fungi. These properties determine the uses of the polymer, especially in electrical and radio engineering, in the chemical industry and medicine.
Известные методы синтеза полифениленоксида основаны на окислительной поликонденсации замешенных моноциклических фенолов и заключаетс в окислении соответствующего фенола кислородом в присутствии катализатора - комплекса соли одиопалеитной меди и первичного, вторичного и третичного амина.The known methods for the synthesis of polyphenylene oxide are based on oxidative polycondensation of mixed monocyclic phenols and consist in the oxidation of the corresponding phenol with oxygen in the presence of a catalyst — a complex of odiopaleic copper and a primary, secondary and tertiary amine.
Было найдено, что смеси металлической меди и солей двухвалентной меди в присутствии аминов и кетонов активно катализируют нроцесс окислительной поликонденсации фенолов, причем активность катализатора усиливаетс с увеличением добавок кетона в реакционную смесь. Изменение соотношени медь металлическа : медь двухвалентна также вли ет на активность катализатора. При увеличении содержани двухвалентной меди в составе смеси металической и двухвалентной меди доIt was found that mixtures of metallic copper and salts of divalent copper in the presence of amines and ketones actively catalyze the process of oxidative polycondensation of phenols, and the activity of the catalyst increases with the addition of ketone to the reaction mixture. A change in the metallic: copper divalent ratio also affects the activity of the catalyst. With an increase in the content of divalent copper in the composition of a mixture of metallic and divalent copper to
70-80% повышаетс выход и молекул рный вес полимера.70-80% increase in the yield and molecular weight of the polymer.
Таким образом, молекул рный вес полифенилеиовых эфиров можно регулировать как изменением соотношени медь металлическа : медь двухвалентна , так и изменением количества кетона. Тот факт, что в присутствии кетонов получают полимер с повышенным выходом и молекул рным весом, позвол ет снизить количество катализатора в реакционной смеси. При этом можно снизить молекул рный вес полимеров до пределов, обеспечивающих хорошую перерабатываемость полимера литьем под давлением и экструзией. Причем упрощаетс отмывка полимера и снижаетс его стоимость.Thus, the molecular weight of the polyphenylene esters can be regulated both by changing the metallic: copper divalent ratio and by changing the amount of ketone. The fact that, in the presence of ketones, a polymer is obtained with an increased yield and molecular weight, it reduces the amount of catalyst in the reaction mixture. At the same time, the molecular weight of polymers can be reduced to the limits that ensure good processability of the polymer by injection molding and extrusion. Moreover, the washing of the polymer is simplified and its cost decreases.
Металлическа медь и соли двухвалентной меди, вл ющиес компонентами предлагаемой каталитической системы, более устойчивы при хранении, чем однохлориста медь, обычно примен ема в качестве катализатора при получении полифениленовых эфиров.Copper metal and salts of divalent copper, which are components of the proposed catalytic system, are more stable during storage than copper monochloride, usually used as a catalyst in the preparation of polyphenylene ethers.
