Title: Flocked materials and their production
Inventor: ZAUNBRECHER HORST
IPC: D04H11/00
Filed: 1965-02-22
Abstract: Flocked material is produced by a process wherein a highly-viscous or thixotropic solution or dispersion, which may contain 10 to 30% by wt. of a readily volatile organic solvent, of a cross-linkable film-forming macromolecular organic substance is flocked with fibres of all types, e.g. cotton, wool, viscose, acetate, triacetate, polyamide, and polyester fibres having any desired shape and colour, and non fibrous materials, e.g. mica and metal powders, by a conventional method, on a non-adherent substrate, and is dried and subjected either before or after stripping from the substrate, to a cross-linking reaction.  The macromolecular organic substance may be a polymer which may be a cross-linkable emulsion polymer, i.e. polycondensation and polyaddition products which after formation of a film can be converted into the thermosetting condition by cross-linking, e.g. unsaturated polyesters, polyurethanes, epoxy resins, and polymers having reactive groups which cause cross-linking, emulsion copolymers of comonomers having reactive groups such as those having free or etherified N-methylolamide, chlorohydrin, epoxy or quaternised dialkylamino methylene amide groups, examples of which are given, or other comonomers which do not contain any groups regarded as reactive in this connection, e.g. butadiene, vinyl esters such as vinyl acetate, styrene, vinyl chloride, acrylic esters, methacrylic esters, fumaric esters, acrylonitrile and methacrylonitrile, acrylic acid, acrylamide and N-vinylpyrrolidone.  The emulsion polymers may themselves be cross-linkable, e.g. contain N-methylol groups, or compounds which cause cross-linking, e.g. dimethylolurea, aminoplast recondensates or diisocyanates, may be added thereto.  Fillers, thickeners, e.g. cellulose derivatives, polyacrylic acid, and polyvinyl alcohol, dyes, brighteners, pigments, protective colloids, plasticizers, hardeners and cross-linking catalysts may also be present.  The solution or dispersion may be applied to the non-adherent substrate by spreading, knife coating or spraying; and is then flocked by scattering or electrostatic means, and any desired pattern being produced by the use of stencils or by applying flock of different types in different patterns.  The non-adherent substrate may be a film or sheet of polyvinyl chloride, polyethylene, polyester, metal, glass or oiled paper.  The organic film may be provided with a self-adhesive layer on the back.

Title: Process for the isomerisation of olefins
IPC: C07C1/32
Filed: 1962-02-27
Abstract: Boron trialkyls in which the alkyl groups correspond to the olefin CH3-CHR-(CH2)n-CH=CH2. in which R is an alkyl group and n is 0 or an integer, are obtained by reacting a boron trialkyl having alkyl groups of 3-5 carbon atoms with an olefin of the formula: CH3-CR=CH-(CH2)n-CH3. Boron tripropyl is the preferred starting material and may be reacted with 2-methylbutene-2, 2-methylpentene-2 or 2-ethylbutene-2 at 100-200 DEG C. and 1-50 atmospheres gauge for 1-8 hours with an olefin to boron mol ratio of 5-10:1. Specification 874,507 is referred to.ALSO:Olefins of the formula CH3-CHR-(CH2)n-CH = CH2 (III) are obtained from olefins of the formula CH3-CR = CH-(CH2)n-CH3 (II) in each of which R is alkyl and n is 0 or an integer, by reaction with a boron trialkyl having alkyl groups of 3-5 carbons to form a boron alkyl corresponding to formula III and recovering olefin III by displacement with another olefin. Preferably olefin II is obtained by isomerisation of an olefin of the formula CH2 = CR-(CH2)n-CH2-CH3 (I) Conversion of olefin I to olefin II is effected with naturally active bleaching earth, e.g. at about 100 DEG  C. in the vapour phase with low-boiling olefins or liquid phase with high-boiling olefins or with silica-alumina.  Reaction of olefin II with, for example, boron tripropyl is effected at 100-200 DEG  C. and 1-50 atmospheres gauge for 1-8 hours with an olefin to boron mol. ratio of 5-10: 1. Olefin III is recovered by reacting the boron trialkyl with, for example, propylene displaced from the boron tripropyl, using a propylene to boron mol. ratio of 15: 1 by injecting the boron trialkyl into a circulating stream of propylene, reacting at 360 DEG  C. and 6 atmospheres for 0.6 second, and separating and recirculating the propylene.  At all stages unconverted materials and reformed compounds are recycled to the appropriate reaction and undesired isomers separated from the desired product after the last stage may be recycled to the first isomerization stage. Specified starting materials are 2-methylbutene-1 and -2, 2-methylpentene-1 and -2 (giving 4-methylpentene-1) and 2-ethyl-butene-1 and -2.  Specification 874,507 is referred to.

Title: Improved anti-halation layers or filter layers for photographic purposes
Filed: 1938-03-14
Abstract: 512,497. Complex metal polyhydroxy compounds. I.G. FARBENINDUSTRIE AKT.- GES. March 14, 1938, No. 7854. Convention date, March 17, 1937. [Class 2 (iii)] [Also in Group XX] A photographic antihalation or filter layer comprises a colloid layer containing a salt of a complex compound of a heavy metal or aluminium and an organic polyhydroxy compound. Suitable organic compounds are sugar alcohols with at least five hydroxyl groups in the molecule, mono-, di- and tri-saccharides and aliaphtic and cyclic poly-hydroxycarboxylic acids such as gluconic, mucic, citric and quinic acids. Alkali, alkaline earth or ammonium salts or salts of aliphatic amines and diamines may be used. The insoluble salts may be added to the colloid layer, for example gelatine, in suspension or may be converted to soluble salts which may be added in solution. This conversion may be effected by causing the insoluble compounds to react with a sulphate of an alkali metal, ammonium or an aliphatic amine or diamine or with a poly-hydroxycarboxylic, acid to form a water soluble compound which may be precipitated with alcohol. In one example, copper sulphate is added to a solution of mannite and the mixture added to caustic soda. Magnesium sulphate' solution is added and magnesium-copper-mannite precipitated. This may be added to gelatine as a suspension. Alternatively, the saccharate or raffinate may be similarly prepared and dissolved in the required quantity of gluconic acid to give magnesiumcopper-saccharose-gluconate which may be precipitated with alcohol and used in aqueous solution. Magnesium-manganese-mannite may be prepared as a precipitate by adding a solution of magnesium sulphate to a solution of mannite in caustic soda in which manganese dioxide has been dissolved. Sodium copper glucose may be prepared by adding magnesium sulphate to a solution containing glucose, copper sulphate and caustic soda. Sodium copper-gluconate may be similarly prepared from gluconic acid.
