| abstract | 520,985. Isomerized rubber. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 7, 1938, No. 32263. Convention date, Nov. 5, 1937. [Class 70] Thermoplastic derivatives are prepared by heating unvulcanized rubber, x or # naphthol and a catalyst selected from sulphuric acid; halogen sulphonic acids, organic sulphonic acids, alkyl sulphates, boron trifluoride, and dihydroxyfluoboric acid. The reaction is carried out below 200C. The amount of naphthol may be 5 to 40 per cent. of the rubber, and-that of the catalyst 2 to 50 per cent. of the naphthol. Free naphthol in the reaction product may be caused to react with an aldehyde such as formaldehyde, furfural, acrolein, butyraldehyde and benzaldehyde. The products are useful for forming moulded articles, coating compositions resistant to acids and alkalies, boxtoes for shoes &c., and for blending with waxy and resinous materials. Specifications 282,778, 307,134, [both in Class 70], and U.S.A. Specification 1,668,236, 1,668,237 and 2,024,987 are referred to. |
