Пример: В реактор загружают .lOO с 5 о-ного paciBopa AlEt;, и 8,2 г Т/С1з в бензине. Через 20 час. ведени процесса при 50° образуетс 350 г полимера. После окоичппи полимеризации реактор ох.таждают до 20 и заливают 40 t эти.тенглпкол . Затем реактор нагревают до 60, При достижении темнературы 70°, производ т отгонку растворител бензина под вакуумом (300-400 мм вод. ст.). По окопчапии отгонки, реактор заполн ют пропиченом или другим инертным газом и заливают метанол в (1,5 л), подкислеппыи ксицентрированпон ПХО ().Example: A .lOO is loaded into the reactor from 5 paciBopa AlEt 5 and 8.2 g of T / C 1 3 in gasoline. In 20 hours Conducting at 50 ° C forms 350 g of polymer. After okoichppi polymerization, the reactor is cooled down to 20 and filled with 40 t of this. Tengpcol. Then the reactor is heated to 60. When the temperature reaches 70 °, the solvent of the gasoline is distilled off under vacuum (300-400 mm wg). After distillation, the reactor is filled with a propylene or other inert gas and methanol is poured in (1.5 l), acidified, and xentered with PCO ().
Отогиалось 450 г бензнна.450 grams of benzene has been added.
Полимер после трехкратно промывки подкисле:п1Ым метано.юм и двукратной промывки чистым метанолом имел зо.чьность ниже 0,1%.The polymer, after three times washing with acidified: p1HM methano.yum and two washes with pure methanol, had a density below 0.1%.
