Title: Improvements in the manufacture and production of polymerisation products from oils and fats
IPC: G06G1/12
Filed: 1930-08-06
Abstract: Polymerization products of fats and fatty oils or their derivatives are made by first forming an aqueous emulsion of the fatty substances if desired with the aid of dispersing agents and thereafter polymerizing the emulsion together with admixed unsaturated polymerizable hydro carbons, in the presence of oxygen or a substance splitting off oxygen.  Vulcanization accelerators such as amines, guanidine or heavy metal salts of fatty acids may be added to the initial materials before emulsification.  The final polymerized emulsion may be used as such or mixed with rubber latex and coagulated by suitable reagents.  Linseed or wood oil or ethylene glycol mono-linoleate is mixed with butadiene or styrene and a small amount of guanidine, and the mixture is emulsified with a dilute solution of ammonium oleate or Turkey red oil.  The resulting emulsion is polymerized by heating with benzoyl or hydrogen peroxide, and the polymerized emulsion is coagulated by addition of a mineral acid, to yield a rubber-like product which may be used in the manufacture of rubber or linoleum.  Specification 322,114, [Class 2 (iii), Dyes &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the treatment of animal or partially polymerized oils such as blown linseed oil, and the use of sulphur or sulphur yielding compounds such as thiosulphates and polythionates as polymerizing agents.  This subject-matter does not appear in the Specification as accepted.ALSO:Polymerization products of fats and fatty oils or their derivatives are made by first forming an aqueous emulsion of the fatty material if desired with the aid of dispersing agents, and thereafter polymerizing the emulsion together with admixed unsaturated polymerizable hydrocarbons in the presence of oxygen or a substance splitting off oxygen.
