Description
Предметом изобретени вл етс способ сополимеризации альфаолефинов друг с другом или с этиленом в присутствии катализатора, образованного металлоорганическим соединением металлов /, // и /// групп таблицы Менделеева,например триалкилалюмипи , галоидных соединений диалкилалюмини или гидридам диалкилалюмини и растворимым в углеводородах соединением переходных металлов IV, V н Vf групп, например: TiCU, VCU, VOCb.The subject of the invention is a method of copolymerizing alpha olefins with each other or with ethylene in the presence of a catalyst formed by an organometallic metal compound //, // and /// groups of the periodic table, for example, trialkyl aluminum, dialkyl aluminum halides or dialkyl aluminum hydrides and hydrocarbon soluble transition metals IV , V n Vf groups, for example: TiCU, VCU, VOCb.
В отличие от ранее известных способов, процесс полимеризации проводитс в автоклавах при низких температурах от +30 до -100°. При этих услови х процесс протекает при полном отсутствии растворителей, а жидка смесь олефипов действует в качестве реакциоппой среды. Отсутствие растворителей благопри тствует высоким выходам сополимера, так как примеси, которые всегда имеютс в растворител х, оказывают действие на катализатор, в особенности при повышепных температурах, уменьша его активность.Unlike previously known methods, the polymerization process is carried out in autoclaves at low temperatures from +30 to -100 °. Under these conditions, the process proceeds in the complete absence of solvents, and the liquid mixture of olefies acts as a reaction medium. The absence of solvents favors high copolymer yields, since the impurities that are always present in solvents have an effect on the catalyst, especially at elevated temperatures, reducing its activity.
Преимуществами предлагаемого способа вл етс то, что получаемые продукты обладают исключительно хорошими свойствами, а их гомогенность благопри тно вли ет на свойства получаемых из них эластомеров . Этот способ вл етс более экономичным, так как не. требует применени растворителей и уменьшаетс расход катализатора.- ., :The advantages of the proposed method are that the products obtained have extremely good properties, and their homogeneity favorably affects the properties of the elastomers obtained from them. This method is more economical since it is not. requires the use of solvents and decreases the consumption of the catalyst. -.:
