Description
Фосфорсодержащие иолимеры получают путем инициированной полимеризации фосфорсодержащих пеиасыщенных кислот, нанрнмер винилфосфониевой, в блоке-расплаве при температурах , превышающих температуру плавлени мономера.Phosphorus-containing iolimers are obtained by initiating polymerization of phosphorus-containing pei-saturated acids, nano-vinylphosphonium, in a melt-block at temperatures above the melting point of the monomer.
Предлагаемый снособ предусматривает в качестве полимеризующейс кислоты применение сб-фепилвииилфосфиновой, что позвол ет получить полностью фосфорилироваиный полистирол, содержащий фосфинокислотную группу у каждого а-углерода винильной группы .The proposed removal method provides for the use of sb-feilviiylphosphinic acid as a polymerizable acid, which makes it possible to obtain a fully phosphorylated polystyrene containing a phosphino acid group in each a-carbon of the vinyl group.
Процесс полимеризации провод т в блокерасилавепри 125-130°С, то есть при температуре , несколько превыщающей температуру плавлепи а-фенилвинилфосфииовой кислоты в присутствии 0,5-4 мол. о/о инициаторов радикальной полимеризации с высокой температурой разложени (перекиси дикумила, гидроперекиси третичного бутила и др.).The polymerization process is carried out in 125-130 ° C blockers, i.e., at a temperature slightly higher than the temperature of the α-phenylvinylphosphinic acid in the presence of 0.5-4 mol. About the initiators of radical polymerization initiators with a high decomposition temperature (dicumyl peroxide, tertiary butyl hydroperoxide, etc.).
Полимеры, получаемые с выходом 90-92%, представл ют собой блоки или белые порошки с содержанием фосфора 16%, обладающие негорючестью и высокой температурой стекловапи (254-290°С). Они растворимы в воде и в спирте и не раствор ютс в кип щем хлороформе . При введении в реакционную смесь небольших добавок дивинилбензола полимеры станов тс нерастворимыми.The polymers obtained with a yield of 90-92% are blocks or white powders with a phosphorus content of 16%, which are incombustible and have a high glass melt temperature (254-290 ° C). They are soluble in water and alcohol and are not soluble in boiling chloroform. When small amounts of divinylbenzene are added to the reaction mixture, the polymers become insoluble.
Гомополимеры а-фенилвинилфосфиновой кислоты могут быть использованы в качестве комплексообразователей, катнонптов, компонентов дл иолученн св зующих и т. д.Α-phenylvinylphosphinic acid homopolymers can be used as complexing agents, catnonpts, components for ibinding binders, etc.
Пример. Гомополимеризацию 40 г (0,22 моль) а-феннлвинилфосфиновой кислоты, дважды нерекрнсталлизованной из хлороформа , с температурой плавлени провод т в блоке-расплаве в атмосфере азота при температуре 125-130 С в присутствии 1,19 г (2 мол. %) перекиси дикумила. После того, как вс реакционна масса затвердеет (ири 130°С), температуру постепенно повышаю до 160°С. Образовавшнйс ири этой температуре красновато-коричневый прозрачный блок после застывамп измельчают, обрабатывают кип щим хлороформом дл удаленн мономера и сущат при 70С. Выход гомополимера составл ет 36,83 г (92% от теоретического). Температура разм гче1И1 полимера , молекул риый вес, определенный методом светорассе ни , равен 16000; содержанне фосфора 16,72%. ИК-спектром и бромнрованием двойные св зи виннльной группы не обнаружены.Example. Homopolymerization of 40 g (0.22 mol) of a-fennvinylphosphinic acid, twice non-recrystallized from chloroform, with a melting point is carried out in a melt-block in a nitrogen atmosphere at a temperature of 125-130 C in the presence of 1.19 g (2 mol.%) Of peroxide dicumila After all the reaction mass hardens (irie 130 ° C), the temperature is gradually increased to 160 ° C. The reddish-brown transparent block formed at this temperature, after frozen, is crushed, treated with boiling chloroform for the removed monomer and maintained at 70 ° C. The yield of the homopolymer is 36.83 g (92% of the theoretical). The temperature of the polymer is more polymer, the molecular weight determined by the light scattering method is 16000; phosphorus content 16.72%. IR spectrum and bromination of the double bonds of the winnile group were not detected.
