Description

Изобретение относитс  к области полимерной химии, в частности к производству полибутадиена, широко примен емого в резиновой и др. отрасл х промышленности.The invention relates to the field of polymer chemistry, in particular to the production of polybutadiene, which is widely used in rubber and other industries.

Известен способ получени  полибутаиёна с использованием катализатора типа катализаторов Циглера-Натта.A known method for producing polybutaiene using a catalyst such as Ziegler-Natta catalysts.

Недостатком способа  вл етс  наличие остатков катализатора в полимере, что обуславливает низкое качество полимера и сужает область его применени . Применение специальных методов очистки полимера от катализатора (промывка растворителем, обработка спиртом и др.) значительно удорожает производство.The disadvantage of this method is the presence of catalyst residues in the polymer, which leads to low quality of the polymer and narrows its scope. The use of special methods for cleaning the polymer from the catalyst (washing with a solvent, treatment with alcohol, etc.) significantly increases the cost of production.

Наиболее близким  вл етс  способ получени  полибутадиена полимеризацией бутадиена в среде углеводородного растворител  в присутствии комплексного катализатора на основе соединени  титана или кобальта, алюминий органического соединени  и полимерного носител , представл ющий собой набухающий в реакционной среде гель.The closest is a method for producing polybutadiene by polymerization of butadiene in a hydrocarbon solvent in the presence of a complex catalyst based on a titanium or cobalt compound, an aluminum compound and a polymer carrier, which is a swelling gel in the reaction medium.

Недостатком известного способа  вл етс  применение в качестве сокатализатора низкомолекул рного металлоорганического соединени  металла I-1I1 группы, которое присутствует в растворе. Это приводит к загр знению полимера металлом НИ группы . Дл  очистки полимера требуютс  специальные технологические операции, например промывка растворителем, обработка спиртом. Кроме того, это обусловливает высокое корродирующее свойство полимеризационного раствора и, следовательно , высокое требование к качеству аппаратуры .A disadvantage of the known method is the use as a cocatalyst of the low molecular weight organometallic metal compound of the I-1I1 group, which is present in the solution. This leads to contamination of the polymer with a metal of the NI group. For the purification of the polymer, special processing steps are required, for example, washing with a solvent, treating with alcohol. In addition, this leads to a high corrosive property of the polymerization solution and, therefore, a high demand for the quality of the equipment.

Целью изобретени   вл етс  упрощение технологии процесса и получение продукта , не требующего отмывки от остатков катализатора.The aim of the invention is to simplify the process technology and to obtain a product that does not require washing from catalyst residues.

Дл  этого в качестве алюминийорганического соединени  примен ют продукт взаимодействи  частично сшитого карбоFor this purpose, a partially crosslinked carbohydrate reaction product is used as an organoaluminum compound.
