Реакцию провод т в бензольном растворе при температуре от-5. до-10°С. Двуокись серы очищают от кислорода щелочным раствором пирогаллола. Присутствие следов гидроперекиси дипзопропилбеизола зиачительно повыщает выход целевого продукта. Полученный полимер- бела воскообразна смола, не раствор юща с в обычных органических растворител х. Полимер не горит и в течение 30 час выдерживает действие концентрированной азотной кислоты.The reaction is carried out in a benzene solution at a temperature of from-5. to-10 ° C. Sulfur dioxide is purified from oxygen with an alkaline solution of pyrogallol. The presence of traces of hydroperoxide dipzopropylbeisol will inevitably increase the yield of the target product. The resulting polymer-white, wax-like resin, which is not soluble in common organic solvents. The polymer does not burn and for 30 hours it withstands the action of concentrated nitric acid.
Пример. Длинную пробирку, снабженную барботером, погружают в охлаждающую смесь, помепщют в нее 60 мл бсизолп п пропускают дпуокись соры. Температуру охлпждпюним cMicn поддсржпплют ОТ--5 до-10°С. После того, как объем содержимого 11 юб11рки увеличитс вдвое, ввод т 15 г триаллилфосфата и несколько капель 30%-ного раствора гидроперекиси диизопропилбензола. Образовавщийс осадок отдел ют от бензола, промывают эфиром и сушат.Example. A long tube, equipped with a bubbler, is immersed in a cooling mixture, 60 ml of hydrochloride is passed into it, and dopoxide is passed through. The temperature of the cooled cMicn is from - 5 to -10 ° С. After the volume of contents of the 11th anniversary doubled, 15 g of triallyl phosphate and a few drops of a 30% aqueous solution of diisopropylbenzene hydroperoxide are introduced. The precipitate formed is separated from benzene, washed with ether and dried.
