Abstract

Latex or a latex concentrate is preserved by adding thereto a small proportion of a sulphonamide or of a mixture of sulphonamides. The sulphonamides specified are p-aminobenzenesulphonamide, 2 - (p - aminobenzenesulphonamido) - pyridine, 2 - (p - aminobenzenesulphonamido) - thiazole, 2 - (p - aminobenzenesulphonamido) - pyrimidine, p - aminobenzenesulphonyl - guanidine, 2 - (p - aminobenzenesulphonamido) - 4 - methyl - pyrimidine, 2 - (p-succinylaminobenzenesulphonamido) thiazole, and 2 - (p - phthalylaminobenzenesulphonamido) thiazole. A solution of a sulphonamide or of a mixture of two to five sulphonamides in aqueous ammonia or sodium hydroxide may be sprayed on to a tapping panel or cut or added to the collecting cup. Suggested mixtures of sulphonamides are described for this purpose and also for addition as preservatives to (a) ammoniated field latex, (b) latex concentrates containing ammonia, and (c) latex or latex concentrate the bacteria in which have been reduced or eliminated by treatment with ultrasonic vibration, ultraviolet irradiation, or high-frequency electric fields.
