Title: Method of treating latex and the products obtained therefrom
IPC: C08C1/02
Filed: 1928-03-19
Abstract: 290,242. United States Rubber Plantations, Inc., (Assignees of Gibbons, W. A., and MoGavack, J.). May 11, 1927, [Conventtion date]. Latex, treating.-Latex which is subsequently to be evaporated, particularly by spraying, so as to retain substantially all the solid constituents, is treated with a substance which prevents coagulation but permits bacterial action and is allowed to stand at ordinary temperature until the protein constituents have been decomposed. Suitable substances are the sodium or potassium salt of sulphonated undecylenic acid, and the resultant product of naphthalene and isopropyl alcohol when treated with sulphuric acid. The decomposition may be that which naturally occurs in course of time or may be accelerated by the addition of digesting material such as pepsin, trypsin or papain, or by small quantities of fecal matter or putrid latex. The final product is light-coloured and translucent, and a dried film has a pitted surface. In an example, 5 per cent of a 10 per cent solution of the sodium salt of sulphonated undecylenic acid is placed in the collecting tank and the latex is added and allowed to stand for from two to five days and then subjected to spray desiccation. In another example, an antiseptic such as formaldehyde is added after the proteins are substantially decomposed to prevent further decomposition. In such a process the formaldehyde may react with amino products formed during the decomposition to produce vulcanization accelerators. In further examples, small quantities of phosphoric or picric acid and, alternatively or in addition, cresol, are added after the decomposition.
