Description

Известно, что при по ении низ«омолекул рных продуктов полимеризации бутадиена или е; :ополимеров в присутствии щелочных металлов или его соединений, л мен емых в качестве пластификаторов, лакового сырь  или компове в смол, образуетс  сырой продукт, содержащий некоторое количест катализатора. Способ очистки указанных продуктов полимеризаци например путем промывани  водой, требуетзначительпого времени.It is known that when the lower molecular weight products of the polymerization of butadiene or e; : polymers in the presence of alkali metals or its compounds, used as plasticizers, lacquer raw materials or resin compounds, a crude product is formed containing a certain amount of catalyst. The method of purification of said products is polymerization, for example by washing with water, requires a significant amount of time.

Предлагаемый спосо 1чистки полимеров или сополимеров бутадиена от щелочных катализ )ров позвол ет значительно упростить технологию очистки, исключить необходимость использовани  дополнительных реагентов и возмон пость загр знени  полимера мылами. Эти преимущества предлагаемого способа достигаютс  тем, что продукт полимеризации раствор ют в Инертном по отнощению к катализатору растворителе и взвеси сорбируют с помощью твердых сорбентов. Предлагаемым сиособом можно получать продукты, значительно превосход щие по своей чистоте, очи-цдаемые известными способами.The proposed method of cleaning polymers or copolymers of butadiene from alkaline catalysts makes it possible to significantly simplify the purification technology, eliminate the need for using additional reagents and the possibility of contaminating the polymer with soaps. These advantages of the proposed method are achieved by dissolving the polymerization product in an inert solvent relative to the catalyst and absorbing the suspension using solid sorbents. With the proposed method, it is possible to obtain products that are significantly superior in their purity and are prepared by known methods.

Пример 1. 100 кг полученного известными приемами сырого продукта полимеризации с в зкостью около 8000 сантипуаз (при температуре 80°) обрабатывают 200 кг петролейного эфира и раствор перемещивают с 5 кг отбельной земли. Частицы гел  вместе с катализатором отдел ют в фильтр-прессе. Затем удал ют растворитель. Количество отделенного гел  составл ет около 3% от веса сырого продукта полимеризацииExample 1. 100 kg of a crude polymerization product obtained by known methods with a viscosity of about 8000 centipoise (at a temperature of 80 °) is treated with 200 kg of petroleum ether and the solution is transferred from 5 kg of bleaching earth. The gel particles along with the catalyst are separated in a filter press. The solvent is then removed. The amount of gel separated is about 3% by weight of the crude polymerization product.

Пример 2. 100 кг сырого продукта полимеризации с в зкостью 3000 сантипуаз (при температуре 80°) перемешивают с 100 кг лакового бензина и 5 кг отбельной земли. После отделени  щлама в емкости дл  отстаивани  и фильтровани  получают раствор продукта полимериза№ 149221Example 2. 100 kg of a crude polymerization product with a viscosity of 3000 centipoise (at a temperature of 80 °) are mixed with 100 kg of lacquer gasoline and 5 kg of bleaching earth. After separating the slurry in the settling and filtering vessel, a solution of the polymerization product No. 149221 is obtained.

ции, освобождаемый в фтарном аппарате от половины присутствующего раствари-тел- и употфбл емый без стабилизации дл  получени  высыхающего лакового сырь .in the fartar apparatus from half of the solvent-tel-solution present and consumed without stabilization to obtain a drying lacquer raw material.
