| titleOfInvention | Improvements in or relating to the treatment of rubber articles |
| abstract | Articles made from polyhaloprene or polymers or copolymers of butadiene which have a surface which has been chemically modified are subjected to oxidation with a solution of an oxidising agent which itself loses oxygen in bringing about oxidation, in an organic solvent until such surface is dissolved or disintegrated. The surface may have been modified with oxygen, light or heat or treated with a halogen, hypochlorous acid or thionyl chloride, or with a cyclising agent such as sulphuric acid or stannic chloride. The oxidising agent may be a permanganate, persulphate, acyl-peroxide, organic per-acid or chromium trioxide as such, or in the form of a chromate or dichromate. The solvents are preferably benzene, acetone and acetic acid. Specifications 403,726, 409,434, 416,154 and 535,983, [all in Group V], are referred to.ALSO:Vulcanized or unvulcanized rubber articles which have a surface which has been chemically modified are subjected to oxidation with a solution of an oxidizing agent which itself loses oxygen in bringing about oxidation, in an organic solvent until such surface is dissolved or distintegrated. The article may be made from natural rubber, gutta-percha, balata or an unsaturated synthetic rubber such as polyhaloprene or a polymer or copolymer of butadiene. The surface may have been modified with oxygen, light, or heat, or treated with a halogen, hypochlorous acid or thionyl chloride; with a cyclizing agent such as sulphuric acid or stannic chloride, or by the methods described in Specifications 403,726, 409,434, 416,154, or 535,983. The oxidizing agent may be a permanganate, persulphate, acylperoxide, organic per-acid or chromium trioxide as such, or in the form of a chromate or a dichromate. The solvents are preferably benzene, acetone and acetic acid. |
