IPC: C08K5/00
Filed: 1960-10-14
Abstract: A pesticide which is a clathrate compound of a pesticidal compound and an amino and/or amido-aldehyde resin is prepared by adding to the monomeric materials to be used for the production of the amino and/or amido-aldehyde resin said pesticidal compound and subsequently polymerizing said monomeric materials. Specified resins are derived from amines and amides such as urea; thiourea; aryl, alkyl or arylalkyl urea or thiourea; melamine; alkyl or aryl melamine; guanidine; alkyl or aryl guanidine; dicyandiamide; biuret; cyanamide; dicyandiamidine or mixtures thereof and aldehydes such as formaldehyde, acetaldehyde, butyraldehyde, crotonaldehyde, benzaldehyde, furfural or an aldehyde source, e.g. hexamethylene tetramine or paraldehyde. Modifying agents which may be included are monohydric alcohols, e.g. ethyl, propyl, amyl, tertbutyl, nonyl, decyl or tridecyl alcohol; polyhydric alcohols, e.g. ethylene glycol, diethylene glycol, glycerol, butane-1,4-diol or pentaerythritol; trace minerals, e.g. cobalt sulphate, copper sulphate, ferrous sulphate, metallic cobalt or iron powder; acetone or cyclohexanone; amides, e.g. formamide, dimethyl formamide, acetamide, stearamide, benzamide or toluene sulphonamide; amines, e.g. ethylene diamine, aniline or phenylene diamines; natural gums and resins, e.g. shellac, rosin, rosin esters and derivatives, gelatin, alginates, cellulose ethers and esters; dyes; fillers, e.g. bentonite; pigments; plasticizers; fatty acids and oils, e.g. oleic, or linoleic acid or other acids, e.g. succinic, malonic, suberic, sebacic, adipic, phthalic or terephthalic acid or phenols or naphthols.  Specified polymerization catalysts are phosphoric acid, sulphuric acid, acetic acid or lastic acid.  A list of numerous pesticidal compounds including insecticides, fungicides, herbicides, nematocides, biocides and plant growth hormones is given (see Group IV).ALSO:A pesticide, which is a clathrate compound of a pesticidal compound and an amino and/or -amido aldehyde resin (see Group IV (a)) is admixed with a solid or liquid carrier for use as a pesticidal composition for agricultural and veterinary use.
