Abstract: Embodiments relate to organometallic compositions that are useful for chain transfer during olefin polymerization. Such compositions are chain transfer agents comprising an organoaluminum compound of the formula Al(CH2CH(Y2)A2)3 and an organozinc compound of the formula Zn(CH2CH(Y2)A2)2.

Abstract: A composition comprising one or more compounds of formula (I) or (II): wherein: Rf is a linear or branched perfluoroalkyl having 1 to 7 carbon atoms, optionally interrupted by one to three oxygen atoms, r and q are each independently an integer of 1 to 3, j is 0 or 1, or a mixture thereof, x is from about 1 to about 2, Z is —O—, —S—, or —NR—, R is hydrogen or an alkyl group containing 1 to 4 carbon atoms X is hydrogen or M, and M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion, and its use in providing surface properties to substrates is disclosed.

Abstract: A process is provided herein for preparing an organo-substituted sodium aluminum hydride by reacting sodium, aluminum, an organic compound of specific structure containing a hydroxyl group and hydrogen.In such process, an aluminum alloy is used as the aluminum.

Abstract: The present invention relates to aluminate coupling agents, their synthesis and applications. Metallic aluminum is reacted with lower alcohols, then reacted with selected longer chain alcohols, phenols, carboxylic acids etc., satisfied the coordination number of aluminum to give aluminate coupling agents having good hydrolytic stability and lower associativity. They can be used directly as typical coupling agents in processing of composition products such as plastics, rubber, coatings and laminates etc., and as adhesive promoter or primer to treat fillers, pigments and various materials in order to improve the processing and the quality of products, to increase the dosage of filler, to develop new products, to reduce energy consuming and cost of products.

Abstract: The invention is directed to a process for the production of aluminium alcoholates by reacting aluminium in comminuted form with an excess of an aliphatic C.sub.3 to C.sub.10 alcohol in which the aluminium is supplied to the reactor from above and is brought into contact with an aluminium alcoholate/alcohol mixture above a perforated plate or grid tray (screen) in the reactor. The aluminium, or preferably a suspension of alcohol and finely divided aluminium, is supplied to the reactor and fed from above to a bubble bed made of a mixture of aluminium alcoholate and alcohol in the area of the perforated plate, whereby the mixture of aluminium alcoholate and alcohol in the reactor sump or overflowing in part is recycled to the reactor over the bubble bed and optionally, preferably with the aluminium suspension, returned from above to the reactor and in part is isolated. There is also described a reactor suitable for carrying out the process.
