| SU1443548A SU417951A3 (en) | 1969-06-03 | 1970-05-27 | METHOD FOR PREPARING ALKYLENE POLYMERS The invention relates to the production of alkylene polymers by polymerization or copolymerization of alpha-alkylenes using a low pressure method on tsigler-tyne catalysts. 120-260 ° C and a pressure of 1 ^ -200 atm in the presence of the reaction product of titanium halides and organoaluminum compounds as the catalyst of the catalyst; and catalyst components are selected between 0.4; 1 and 1,4: 1. When choosing a different value for the ratio of 15, the polymerization rate decreases rapidly, the degree of polymerization is poorly controlled and the polymerization product is obtained with undesirable flow properties. According to the invention, it was found that when the alkylene polymerizes in a liquid disnergator with an increased the temperature and the use of the catalyst obtained by mixing the components in a certain ratio are obtained by polymerization, containing a small amount of catalyst residue, which can not be removed. The catalyst, we use th in the proposed method, it is very active. The resulting polymer has a good flow property 30 and is suitable for many working purposes. The catalyst used consists of titanium halogen of the compound of the general formula A1Ks -, „X,„, in which R is a hydrocarbon radical GI — Сзо; X is a halogen atom; t is a number from 1 to 3 (inclusive), and the organomagnesium compound, and the molar ratio between the magnesium and aluminum compounds corresponds to the formula (m - A): B, in which m means the number of halogen atoms per one aluminum atom of the aluminum compound, A is the number between minus 0.75 and 0.97 and B is a number between 2.2 and 2.7, alley molar ratio between the aluminum compound and titanium is selected between 8 and 2000. As an aluminum compound with the general formula AIRa-mX, »can be used trigalo- aluminum halides such as aluminum trichloride or aluminum tribromide, or organo-aluminum halide. Mixtures of aluminum 11 can also be used. Suitable organoaluminum halides contain, on average, at least one or, in extreme cases, two halogen atoms and, at least directly with the carbon atom, a hydrocarbon radical attached to aluminum. The hydrocarbon radical can mean an alkyl, cycloalkyl, alkaryl, aryl, or aralkl group. Examples |
