    Abstract: The invention comprises compounds of the general formula: in which R and R1 are identical or different aliphatic radicals having one to four carbon atoms and which may bear alkoxy groups or dialkylamino groups, and R2 and R3 are the same or different and denote hydrogen, aliphatic, cycloaliphatic, arylaliphatic or aromatic radicals which may bear halogen or alkoxyl or dialkylamino groups. The new compounds may be made by reaction of N,N1-disubstituted formamidines of the formula R-N=CH-NHR1 with an isocyanate R2NCO or a carbamyl chloride Cl-CO-N(R2)R3 and an alkaline compound. Suitable starting materials are specified. The reaction is effected at temperatures between 0 DEG and 150 DEG C., in inert solvents. Detailed examples are given. The products are used in herbicidal compositions.ALSO:A herbicidal composition comprises a compound of the formula in which R and R1 are identical or different aliphatic radicals having one to four carbon atoms and which may bear alkoxy groups or dialkylamino groups, and R2 and R3 are the same or different and denote hydrogen, aliphatic, cycloaliphatic, arylaliphatic or aromatic radicals which may bear halogen or alkoxyl or dialkylamino groups, and a carrier therefor. The compositions may be formulated as solutions, emulsions, emulsion concentrates, pastes, wettable powders, granules, suspensions or dusts. Suitable solvents are mineral oil fractions, animal or vegetable oils, cyclic hydrocarbons, alcohols, ketones, ethers, hydrocarbons, and chlorinated hydrocarbons. Quaternary ammonium compounds, soap, aliphatic sulphuric acid monoesters, aliphatic aromatic sulphonic acids, lignin-sulphonic acid, alkoxy-acetic acids, polyethylene ethers of fatty alcohols and polyethylene oxide condensation products may be used as emulsifying and dispersing agents. Solid carriers specified are talc, diatomaceous earth, kaolin, bentonite, calcium carbonate, boric acid, calcium phosphate, wood flour, cork flour, carbon and ammonium sulphate. Other substances which may be present are fatty acids, resins, glues or alginates, phenoxycarboxylic acids, substituted carboxylic anilides, triazine derivatives, urea derivatives, e.g. N-p-chlorophenyl-N1-methyl, N1-isobutinyl urea and N-cyclooctyl, N1,N1-dimethyl urea, chlorinated fatty acid esters, anhydrobenzoylanthranilic acid, bactericides, fungicides and fertilizers. Detailed examples are given.

    IPC: C08G69/20

    Abstract: In a process for the anionic polymerization of lactams having 5 to 14 ring members, the polymerization activator used is a compound of the general formula where n is 1 or 2, R1 and R2 are each monovalen hydrocarbon radicals having one to seven carbon atoms or R1 and R2 joined together form a divalent radical, R3 is hydrogen or a hydrocarbon radical having one to eight carbon atoms and R, when n is 1 is an alkyl amine, arylamino or aralkylamino radical having one to fourteen carbon atoms, and, when n is 2 is a divalent radical having the formula -NH-R3-NH- where R4 is a divalent hydrocarbon radical having two to fifteen carbon atoms. Specified lactams are pyrrolidone, piperidone, e -caprolactam, capryllactam, oenanthiclactam, capriclactam, laurolactam, e -ethyl-e -caprolactam, #x-ethyl-#x-oenantholactam and methylenebis-caprolactam. Fillers, e.g. glass fibres, asbestos, graphite, gypsum, chalk, molybdenum sulphide, wood flour and fibres may be incorporated into the polymerization mixture. In Examples (1) to (6), e -caprolactam is polymerized in the presence of sodium caprolactam and: (1) benzimidazole-1-carboxylic anilide; (2) imidazole-1-carboxylic acid N : N1-diphenyl amide; (3) benzimidazole-1-carboxylic acid (N1-methyl) anilide; (4) 2-methylimidazoline-N(1)-carboxylic acid N : N1-diphenyl amide; (5) N : N - hexamethylene - bis - (carbamyldimethyl formamidine) and (6) (a) hexamethylene - bis - (N1 - carbamyl - 2 - methylimidazoli (b) hexamethylene-bis-(N-carbamyltriphenyl formamidine). In Example (7) pyrrolidone is polymerized in the presence of sodium methylate and imidazole-1-carboxylic diphenylamide.
