Description
(54) СПОСОБ ПОЛУЧЕНИЯ ХЛОРСОДЕРЖАЩЙХ КАРБОЦЕПНЫХ ПОЛИМЕРОВ рации эмульгатора 5 вес, ч. Дл реакции берут 15 г мономера, 27 мл дистиллированной воды, 0,147 г персульфата кали , 0,75 г мерзол та. Реакцию провод т при посто нном перемешивании 5 ч при 50 С затем 1О ч при 20 С. Эмульсию разрушают метанолом. Полимер отдел ют фильт рованием, промывают водой, спиртом, переосаждают . Получают 13,2 г {88% кау чукоподобного полимера светло-желтого цвета. Найдено, %: С 42,37; Н 4,04; С1 52,99, Вычислено, %: С 43,70; Н 4,37; С1 52,10. Характерчстическа в зкость в бензоле при 25С q 0,4 дл/г. Пример 2, Полимеризаци 3-хлорметилхлоропрена в блоке. Дл реакции берут 4,5 г мономера. Реакцию провод т в запа нной вакуумированной ампуле при 25 С в течение 65 ч. Полимер раствор ют в хлоро4)Орме и осаждают спиртом. Получают 3,2 г (71%) каумукоподобпого полимера, 0,3 an/г, С 42,55; Н 4,54; Найдено, % С1 ,27. С 42,54; Н 4,38; Вычислено, С1 52,L Пример 3. Полимеризаци 3 -хлорметилхлоропрена в растворе. Дл реакции берут 7 г мономера и 0,О617 г (0,5 мол, %) перекиси бензола в 7 мл бензола (концентраци раствора 4 моль/л). Реакцию провод т в запа нной вакуумированной ампуле при 5О С в течение 5 ч. Полимер осаждают метанолом. Получают 5,3 г (72%) каучукоподобного полимера f j 0,2 дл/г. Свойства полимеров, полученных по известному и предлагаемому способам, приведены в таблице.(54) METHOD OF OBTAINING CHLORINE-CONTAINING CARBOCEPRIC POLYMERS of emulsifier radiator 5 weight, h. For the reaction, 15 g of monomer, 27 ml of distilled water, 0.147 g of potassium persulfate, 0.75 g of ground mineral are taken. The reaction is carried out under constant stirring for 5 hours at 50 ° C and then 1O hours at 20 ° C. The emulsion is destroyed with methanol. The polymer is separated by filtration, washed with water, alcohol, and reprecipitated. 13.2 g {88% light yellow color caustic polymer is obtained. Found,%: C 42.37; H 4.04; C, 52.99; Calculated,%: C, 43.70; H 4.37; C1 52.10. The characteristic viscosity in benzene at 25 ° C is 0.4 dl / g. Example 2 Polymerization of 3-chloromethyl chloroprene in the block. 4.5 g of monomer is taken for the reaction. The reaction is carried out in a vacuum ampoule sealed at 25 ° C for 65 hours. The polymer is dissolved in chloromerme) and precipitated with alcohol. 3.2 g (71%) of a kaumuk-like polymer are obtained, 0.3 an / g, C 42.55; H 4.54; Found,% C1, 27. C 42.54; H 4.38; Calculated, C1 52, L Example 3. Polymerization of 3-chloromethylchloroprene in solution. For the reaction, 7 g of monomer and 0, O 617 g (0.5 mol,%) of benzene peroxide in 7 ml of benzene (concentration of the solution 4 mol / l) are taken. The reaction is carried out in a vacuum ampoule sealed at 5 ° C for 5 hours. The polymer is precipitated with methanol. This gives 5.3 g (72%) of a rubbery polymer f j 0.2 dl / g. The properties of the polymers obtained by the known and proposed methods are shown in the table.
