Title: Hydrogentated graft copolymers
IPC: C08F8/04
Filed: 1970-06-22
Abstract: 1311304 Hydrogenated graft polymer BORGWARNER CORP 22 June 1970 [27 June 1969] 30080/70 Heading C3G A hydrogenated thermoplastic graft copolymer is prepared by hydrogenating a polymeric substrate graft polymer represented by the formula A(B) x , wherein "A" is a polymeric backbone prepared from at least one monomer selected from substituted and unsubstituted conjugated dienes, substituted and unsubstituted monovinyl aromatic hydrocarbons; wherein "B" is a pendant linear polymeric chain grafted on said "A" backbone by anionic polymerization of at least one anionically polymerizable monomer selected from substituted and unsubstituted conjugated dienes and substituted and unsubstituted monovinyl aromatic hydrocarbons; and wherein "x" is a positive integer. The hydrogenation may be either complete or partial producing either monovinylaromatic substituted ethylene graft copolymers or vinyl cyclohexane substituted ethylene graft copolymers. In the preparation of the graft copolymer, prior to hydrogenation, the backbone chain may be prepared by any convenient process, after which it is dissolved or suspended in an inert hydrocarbon solvent and treated thereafter with a suitable reagent such as an organo alkali metal diamine complex to introduce active organometallic sites along the backbone chain, after which the grafting monomer(s) are added. The examples refer to partially hydrogenated graft copolymers formed from (a) styrene and 1,4- polybutadiene having respectively the following number of grafting sites, the specific examples being referred to thereafter in brackets: 3(1, 15), 7(3), 10(2, 6, 11, 14, 16), 15 (19), and 35 (13); (b) styrene and 17% 1,2-polybutadiene 10 (4, 7); (c) styrene and 60% 1,2-polybutadiene: 3 (8), 10 (5, 10, 12); (d) styrene and 64% 1,2- polybutadiene: 6(9); (e) styrene and cis polybutadiene: 10 (17); (f) styrene and cis polyisoprene: 10(18); (g) styrene and 20% styrenebutadiene styrene block copolymer: 10 (21); and (h) 40% styrene-butadiene block copolymer and styrene: 10 (20). In these examples the active sites on the polymer backbone are formed by using an organometallic catalyst formed from see-butyllithium and tetraethylene diamine whilst the hydrogenation catalyst comprises a mixture of cobalt octoate and triethyl aluminium. Fully hydrogenated graft copolymers are formed from (i) styrene and 1,4-polybutadiene and 3 (26), 7 (22, 23, 29), 10 (24, 27, 28); and (j) styrene and 63% 1,2-polybutadiene: 7 (25), in which the grafting sites are formed as in Examples 1 to 22 but using the hydrogen catalyst under a greater pressure and elevated temperature in an autoclave.

Abstract: 262,141. I. G. Farbenindustrie Akt.- Ges., (Assignees of Akt.-Ges. f³r Anilin- Fabrikation). Nov. 28, 1925, [Convention date]. Thiazoles.-Thiazole derivatives of 1: 4-naphthoquinone are obtained by condensing 2 amino- 3-mercapto-1 : 4-napthoquinone with an aldehyde. The intermediate products first obtained pass into thiazoles by the action of atmospheric oxy- and may be used directly for vat dyeing. In an example, 2-amino-3-mercapto-1: 4.naphthoquinone is condensed with benzaldehyde; greenish-yellow crystals are obtained which form a blue-red vat, dyeing cotton a greenish yellow. fast to chlorine and soap, when dissolved in caustic soda and hydrosulphite. The finished dyestuff may be obtained by introducing air into the solution. The properties of the thiazole derivatives obtained from the following aldehydes are tabulated :-Glyoxal, 1-naphthaldehyde, artetrahydronaphthalene-1-aldehyde, 4-aminobenzaldehyde, 4-dimetbylaminobenzaldehyde, 2.chlor- 4-dimethylaminobenzaldehyde, and terephthalic aldehyde. Some of the products dye animal fibres as well as vegetable fibres in the vat. and compounds containing sulpho groups, e.g. the product obtained by condensing 2-amino-3-mercapto-1: 4-naphthoquinone with benzaldehyde sulphonic acid, dye wool without being previously vatted. 2-Amino-3-mercapto-1 : 4-naphthoquinone is obtained by treating 2-amino-3-chlor-1 : 4-naphthoquinone with sodium sulphide. ar-Tetrahydronaphthalene-1-aldehyde is made from tetrahydronaphthalene by converting it into its 1-#-aminomethyl derivative (by condensing with #-chlormethylphthalimide and treating the product in succession with an alkali and an acid, according to the process described in Specification 249,883), condensing with 4-nitra-1-chlorbenzene-2-sulphonic acid, and oxidizing the product by means of bichromate and sulphuric acid.

IPC: B02C9/02
Filed: 1927-11-12
Abstract: 292,838. Booth, V., and Booth, W. Nov. 12, 1927. Scouring and polishing; magnetic treatment.- Maize or other grain passes from a hopper 1 down a square pipe 2 through an adjustable aperture between a slide plate 13 and a rotating roller past a series of horse-shoe magnets by which particles of iron are removed. The pipe 2, which is perforated as shown at 54, directs the grain through an opening in a stationary cutter disc 3 into the central space between this disc and a co-operating rotary disc 4. The discs 3, 4 are also spaced by chilled steel plates having radial saw-teeth cut round the outer portions of their opposite inner faces. The outer cutting portions are parallel but the inner portions are bevelled to merge into central recessed parts of the discs into which the grain is fed. Bolts rigidly fixed near the periphery of the disc 3 pass longitudinally through hollow bolts 19 screwed into the side wall 5 and are provided with nuts. The combination of the two sets of bolts permits complate adjustment of the disc 3 relatively to the disc 4. The disc 4 is similarly attached to a circular supporting plate 25 secured to a shaft 11. The shaft 11 may be longitudinally adjusted by a hand-screw 30 provided with a locking-nut 31 and acting through a ball-bearing thrust-block 27. A helical spring 35 normally tends to hold the discs apart. Blades or vanes 34 are attached to the ends of radial arms 33 on the back of the plate 25 to scour or beat the grain. The fine dust is driven off through the perforated casing. Dust is also removed from the casing 6 thrcugh a pipe 42 leading to a suction fan 43. The grain escapes past an adjustably weighted door 37 into a chamber 45 that is also connected by a pipe 46 to the fan 43. The blades 34 are preferably inclined to force the grain past the weighted door 37. A light external casing 44 surrounding the casing 6 is provided with a dust outlet 56.

The binder may be thermoplastic or thermosetting and in the form of a powder or a liquid emulsion. The fibres are preferably continuous glass strands deposited in random array. Where short fibres are used either a coherent layer e.g. a continuous strand mat is incorporated to allow the mat to be drawn through the apparatus by rolls 18, 19 or guiding faces are used which move in the same direction as the mat moves. Thus one guide may be a roller and the other an endless band. Alternatively a guide may move with the mat whilst in contact with it then be withdrawn from the mat and move in the opposite direction before contacting the mat again at the beginning of another cycle. In the illustrated embodiment guides 9, 10, 11, 12, 16 and 17 are kept cool by coolant flowing through jackets 24, 25, 26, 27, 40 and 41. Hot air under pressure passes from header 28 via a line of ports 29 and mainly passes upwards through the gap between heated guides 14, 15. Cold air under pressure passes from duct 30 through ports 31 and mainly passes downwards through the gap between guides 16, 17. Air is also supplied by headers 36, 37 and air is used to carry powdered thermoplastic binder from header 21. The air flows distribute the binder. Preferably continuous bundles of fibres 1, 2 are drawn of the outside of cheeses rotated at constant speed by the apparatus of Fig. 4 (not shown) and fed by compressed air through bell shaped expansion chambers 3, 4, to be deposited on tables 5, 6. Devices 3, 4 may oscillate across the width of the tables, or a plurality of devices may be arranged across each table. The tables are wider than the webs 7, 8 and have curved edge portions 61, 62 which bend and fold inwards the edges of the mat, to give a uniform weight/ unit area mat.
