Description
3 под вакуумом при 20°С. Выход полимера3 under vacuum at 20 ° C. Polymer yield
Полимер растворим в воде, спиртах, диметилформамиде .The polymer is soluble in water, alcohols, dimethylformamide.
Приведенна в зкость 0,5%-ного раствора в воде 0,52 дл/г; содержание хлора 36%.The reduced viscosity of a 0.5% aqueous solution is 0.52 dl / g; chlorine content 36%.
Статическа обменна емкость по 0,1 н. раствору AgNOa И мг-экв/г; приведенна в зкость в 0,1 н. растворе КС1 0,22 дл/г.Static exchange capacity 0.1 n. AgNOa solution And mg-eq / g; reduced viscosity 0.1 n. a solution of KCl 0,22 DL / g
Пример 2. В трехгорлую колбу, снабженную мешалкой и капельной воронкой, помещают 6 г (12 мл) 50%-ного раствора этилендпамина (0,1 моль) в воде, 20 мл этилового спирта, затем смесь охлаждают льдом до 5°С и при медленном перемешивании по капл м приливают 12,9 г 1,3-дихлоргидрина и 20 мл этилового спирта. Реакцию поликоидепсации провод т при температуре 20°С в течение 8 ч, отгон ют растворитель. Полученную светло-коричневую полимерную массу обрабатывают сухим бензолом или петролейным эфиром, сушат в вакууме при 20°С.Example 2. In a three-necked flask equipped with a stirrer and an addition funnel, placed 6 g (12 ml) of a 50% aqueous solution of ethylene papamine (0.1 mol) in water, 20 ml of ethyl alcohol, then the mixture is cooled with ice to 5 ° C and 12.9 g of 1,3-dichlorohydrin and 20 ml of ethyl alcohol are added dropwise while stirring slowly. The polycoidepsy reaction is carried out at a temperature of 20 ° C for 8 hours, the solvent is distilled off. The resulting light brown polymer mass is treated with dry benzene or petroleum ether, dried in vacuum at 20 ° C.
Выход полимера 96%.The polymer yield 96%.
Приведеппа в зкость 0,5%-ного раствора в воде 0,45 дл/г; содержапие хлора 34,3%.The viscosity of a 0.5% solution in water is 0.45 dL / g; chlorine content 34.3%.
Статическа обменна емкость по 0,1 н. раствору AgNOa 9,8 мг-экв/г; приведенна в зкость в 0,1 н. растворе KCI 0,19 дл/г.Static exchange capacity 0.1 n. AgNOa solution 9.8 mg-eq / g; reduced viscosity 0.1 n. a solution of KCI 0,19 DL / g
Полимер растворим в спиртах, воде, диметилформамиде .The polymer is soluble in alcohols, water, dimethylformamide.
Синтезированные полиэлектролиты обладают высокоэффективным флокулирующим действием, превышающим флокулирующее действие известных водорастворимых полиэлектролитов .Synthesized polyelectrolytes have a highly effective flocculating effect, exceeding the flocculating effect of the known water-soluble polyelectrolytes.
