Description
Известны способы полимеризации олефинов в высокомолекул рные продукты (типа пластмасс) в присутствии металлалкилов и соединений т желых металлов в качестве катализаторов.Methods are known for the polymerization of olefins into high molecular weight products (such as plastics) in the presence of metal alkyls and heavy metal compounds as catalysts.
Также известно применение в качестве катализаторов дл полимеризации олефинов алюминийтриалкилэтилового эфира, однако при этом получают сравнительно низкомолекул рные продукты. It is also known to use aluminum trialkyl ethyl ethers as catalysts for the polymerization of olefins, but relatively low molecular weight products are obtained.
Предлагаетс способ полимеризации олефинов (например, этилена, пропилена, бутилена и т. п.) в высокомолекул рные продукты (типа пластмасс) в присутствии катализаторов, представл ющих собой триалкилалюминий-алкиларилзфираты или алкилгалогенидалюминий-алкиларилэфираты или их смеси в сочетании с некоторыми сол ми т желых металлов, таких, как четыреххлористый титан или цирконий.A method is proposed for the polymerization of olefins (for example, ethylene, propylene, butylene, etc.) into high molecular weight products (such as plastics) in the presence of catalysts that are trialkyl aluminum-alkylaryl ethers or alkyl halide aluminum-alkyl aryl ethers or their mixture in combination with some salts metals such as titanium tetrachloride or zirconium.
Полимеризацию провод т при температурах до 200° (преимущественно в пределах ) и при нормальном или повыщенном (до 500 атм) давлении в присутствии подход щего растворител или при отсутствии такового.The polymerization is carried out at temperatures up to 200 ° C (preferably within) and under normal or increased (up to 500 atm) pressure in the presence or absence of a suitable solvent.
. Предлагаемый способ получени катализаторов дает возможность упростить и ускорить процесс. Изготовленные по этому способу катализаторы по своей каталитической активности не уступают алюминийтриалкилам .. The proposed method for producing catalysts makes it possible to simplify and speed up the process. Catalysts manufactured by this method are not inferior to aluminum trialkyls in their catalytic activity.
Кроме того, по сравнению с огнеопасными алюминий-триалкилами они обладают тем преимуществом, что не возгораютс самопроизвольно, что значительно упрощает обращение с ними на практике.In addition, compared with flammable aluminum-trialkyls, they have the advantage of not spontaneously combusting, which greatly simplifies the handling of them in practice.
Пример 1. В стекл нную колбу с мещалкой ввод т 3,5 л безводного легкого бензина, 8 г алюминий-триэтиланизолэфирата и 5 г четыExample 1: 3.5 liters of anhydrous light gasoline, 8 g of aluminum-triethyl anisoleate and 5 g of couple are introduced into a glass flask with a baffle.
