Abstract
1,053,336. Slow-release fertilizers. BADISCHE ANILIN- & SODA FABRIK A.G. March 12, 1964 [March 14, 1963], No. 10450/64. Heading ClB. A fertilizer is coated with 2-20% of a composition comprising 45-85% of a polyene polymer containing vinyl groups and 10-50% of a drying oil containing at least two conjugated double bonds in the molecule and the coating is cured. A slow-release fertilizer is thereby produced. The composition may also contain 5-45% of a lipophilic aminoplast precondensate. The fertilizer may contain an alkali metal, an alkaline earth metal, ammonium, phosphate, nitrate, chloride, sulphate, carbonate, or urea. The polymer may be derived from butadiene, isoprene, piperylene, 3-methyl-heptatriene-1,4,6, or w-decatriene-1,5,9. Copolymerization may be effected with up to 50% of ethylene, propylene, butylene, isobutylene, vinylacetylene, styrene, α-methylstyrene, acrylonitrile, an ester of acrylic acid or methacrylic acid, a vinyl ether or ester, or a vinylidene halide. The drying oil may be oiticica, castor, or wood oil. The aminoplast precondensate may be derived from formaldehyde and urea, thiourea, melamine, benzoguanamine, ammeline, guanidine, dicycanodiamide, glyoxyl monoureide or diureide, or N,N<SP>1</SP>-dimethylurea. The coating may be cured by heating at 60-150‹ C. for 2-20 mins. Curing may be effected in the presence of cobalt naphthenate as dryer, a peroxide or hydroperoxide as free radicalforming substance, or dimethylaniline as accelerator. A plurality of coatings may be applied.
