Title: Improvements in or relating to the production of artificial leather
IPC: D06N3/00
Filed: 1928-12-03
Abstract: 301,759. Compagnie Francaise d'Exploitation des ProcÚdÚs Plinatus, (Assignees of Plinatus, W.). Dec. 3, 1927, [Convention date]. Plastic compositions containing cellulose esters, ethers &c.-Artificial leather is made by applying semi-solid layers of cellulose esters or ethers to a base by placing the base and the coating layer between two plates adapted to be heated or cooled and drawing the plates and the material between rollers. Cellulose esters such as nitro-cellulose or acetyl cellulose ethers such as ethyl cellulose, are kneaded, in moist state but without solvents, preferably in a vacuum, with softening and gelatinizing agents. Esters of polyvalent alcohols, for instance, phthalic acid ethyl ester, or animal or vegetable oils, glycerine, or glycol or glycol esters, may be used as such agents. The temperature of the kneaded mass is reduced, and it is then rolled into thin sheets. The sheets, togehter with the base, are then passed through the apparatus shown diagrammatically in the Figure. The base 5, which may be fabric, paper, leather, &c., is taken from a roll 7 and led over a movable table 3 provided with heating and cooling means. The cellulose sheet 4 is taken from a roller 6 and led between the base and an upper metal plate 2 which is also provided with heating and cooling means. The table 3 and the plate 2 are pressed together by means of rollers 1, 1. The plate 2 is preferably engraved with a pattern to emboss a grain upon the material. The rollers are then caused to move to and fro, so that the coating material and the base are firmly united. The upper plate 2 is then cooled. The plates may be two or three metres long, and bent upwardly and downwardly at one end as shown.

Title: A process for the copolymerization of esters containing unsaturated fatty acid groups
IPC: C08F299/02
Filed: 1959-10-26
Abstract: Esters containing ethylenically unsaturated fatty acid groups having at least 8 carbon atoms in the group are copolymerized with a substituted or unsubstituted hydrocarbon in the presence of from 0,03 to 1,5% by weight of the reactants of iodine. Hydrocarbons specified are styrene, alpha-methyl styrene, vinyl toluene and their chloro-, bromo-, methoxy and alkyl derivatives, butylene, butadiene, isoprene, dimethyl butadiene, and cyclopentadiene.  Unsaturated fatty acid groups specified are those derived from linseed, dehydrated castor, sunflower, tung, talc and oiticica oils, which are used in the form of their esters with:-(1) glycerol, pentacrythritol, mannitol, sorbitol, trimethylol propane and butanetriol, (2) epoxy resins obtained by reacting polyhydric phenols, e.g. 2, 2-bis(4-hydroxyphenyl) propane, or polyhydric alochols with epichlorhydrin or dichlorhydrin, or (3) alkyd resins, e.g. a glycerol/phthalic anhydride condensate, or phenol-formaldehyde resins.  The iodine, which may be replaced by a compound yielding iodine under the reaction conditions, e.g. hydriodic acid, prevents the homopolymerization of the unsaturated hydrocarbon.  The reaction is preferably carried out at a temperature between 225 DEG  and 300 DEG C.  The products may be used in coating applications.  The examples describe (1) the copolymerization of styrene and linseed oil, and (2) the copolymerization of styrene with the linseed oil acid ester of an epoxy resin.
