Abstract: A process for the production of carbonyl-iron-silicide involves heating a mixture containing (a) 20-99.9 wt% finely-divided carbonyl-iron and (b) 0.1-80 wt% finely divided silicon powder. An Independent claim is also included for carbonyl-iron-silicide obtained by this process.

Abstract: A process for producing phosphorus-containing iron powder involves heating a mixture of finely divided carbonyl iron and elemental phosphorus and pulverising the product. Preferably, a mixture of 70-99 wt.% finely divided carbonyl iron powder and 1-30 wt.% red phosphorus is heated at above 300 degrees C in an inert gas atmosphere. Also claimed is a phosphorus-containing iron powder of less than 10 mu mean particle diameter, containing 0.1-80 wt.% P, less than 1 wt.% C, less than 1 wt.% N, less than 0.5 wt.% H and less than 0.1 wt.% total of other impurity elements except oxygen.

Abstract: Ziegler-Natta catalyst system, contains (a) a titanium-containing solid component derived from a titanium compound, a magnesium compound, a halogenating agent and an electron donor, (b) an aluminium compound and (c) an organosilicon compound of formula R R Si(OR )2 (I) as additional electron donor, in which R = 1-10C alkyl or 3-8C cycloalkyl; R = 2,4,4,6,6-pentamethylheptyl; R = 1-8C alkyl. Also claimed is (i) a process for the production of polymers from 2-10C alk-1-enes by polymerisation for 1-10 hours at 20-150 degrees C and 1-100 bar in presence of this catalyst system; (ii) polymers of 2-10C alk-1-enes obtained by this process; and (iii) film, fibres and mouldings obtained from these polymers.

Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.
