Abstract: A liquid polymer having a very high viscosity of between 250 cSt and 15,000 cSt at 210 DEG F, is prepared by polymerizing one, or a mixture of more than one, n-alpha olefine represented by the formula R - CH = CH2, in which R is an alkyl radical containing from 6 to 8 carbon atoms, in the presence of a catalyst system formed at a temperature in the range of 0 DEG -150 DEG C by a catalyst consisting of TiCl4 and a polyiminoalane having the formula: --Al---N-- ¦¦ HR n IN WHICH N IS A WHOLE NUMBER NOT GREATER THAN 50 AND R is an isopropyl radical, and in an atmosphere consisting essentially of an inert gas. The liquid polymer of very high viscosity so formed is useful as a lubricant.

Abstract: The mechanical and thermal properties of aluminum oxide, such as gamma alumina, adapted for use as a catalyst or catalyst carrier are improved through a treatment thereof with a silicon compound such as an alkyl orthosilicate in which the aluminum oxide is impregnated with the silicon compound or a solution thereof in a compatible organic solvent whose boiling point is lower than the boiling point of the silicon compound. The impregnated aluminum oxide is dried at a temperature in the range from above the boiling point of the silicon compound to 500 DEG C and is then subjected to controlled oxidation.

Abstract: A method is disclosed for preparing tertiary olefins starting from the corresponding tertiary ethers, the improvement consisting in contacting the ether with a catalyst composed by active alumina modified by reaction with a silicon compound selected among those corresponding to the general formula: wherein X,Y,Z and W can be -R, -OR, -Cl, -Br, -SiH3 , -COOR, -SihnOm, R being hydrogen, an alkyl, cycloalkyl, aryl, aralkyl or alkyl-cycloalkyl radical of from 1 to 30 carbon atoms, n and m being integers comprised between 1 and 3. The advantages afforded by the invention are mainly the nearly quantitative yields and the high purity of the end products.
