Abstract: 1,2,4-triazole is obtained by cyclization of N,N'-diformylhydrazine with ammonia in the presence of formamide. The amount of ammonia required is either formed in situ from thermally decomposable ammonium salts, or supplied by feeding in gaseous ammonia. Simultaneously, the water of reaction is constantly distilled off from the system.

Abstract: Ethylene and vinyl sulphonamide are copolymerized in the presence of a free-radical-forming compound as catalyst at a pressure above 10 atmospheres. The polymerization is preferably carried out at a temperature of 20 DEG to 250 DEG C. in the presence of an inert solvent. The usual free-radical catalyst are used.

Abstract: By reacting polyalkyl-piperidones-4 with the 0.5- to 1.1-molar amount of formaldehyde in the presence of an aliphatic monoalcohol at 50 DEG to 180 DEG C., polymers of a polymerization degree of from 2 to about 200 are obtained, which may be hydrogenated or partially hydrogenated. Especially in this form, they are suitable as light stabilizers for synthetic polymers and as intermediate products for the preparation of other stabilizers for plastic materials.

Abstract: 1,128,304. Ethylene/maleic anhydride/dicyclopentadiene terpolymers. FARBWERKE HOECHST A.G. 7 Feb., 1966 [5 Feb., 1965], No. 5244/66. Heading C3P. A high molecular weight terpolymer of ethylene, maleic anhydride and 0À01-2À5% by wt. of dicyclopentadiene is claimed. The terpolymer may be prepared by copolymerizing the monomers in the presence of a free-radical initiator, e.g. benzoyl peroxide or azobisisobutyronitrile and a solvent or diluent, e.g. benzene, at an elevated temperature and preferably under an elevated pressure. In a comparative example the dicyclopentadiene was replaced by hexadiene-1,5.

Abstract: Low-melting, easily processable and at the same time hard polar waxes are obtained by treating copolymers, which are composed of ethylene and 0.5 to 50% by weight of a monomer containing oxygen-containing groups and have melt indices (MFI 190/2) of between 0.01 and 400 g/10 minutes, in the molten state, dispersed in a dispersing agent which is inert towards oxygen, with oxygen or oxygen-containing gases. Preferably, ethylene/vinyl acetate copolymers are oxidized, and these oxidation products are particularly suitable as the wax component in water-based and/or organic solvent-based polishes and in pastes.

Abstract: The invention provides novel organotin compounds and their preparation by reaction of organotin halides with mercaptans, thiocarboxylic acid esters, carboxylic acids or carboxylic acid partial esters. Suitable organotin halides are those obtained by reaction of Sn+HCl with an olefin which carries a carbonyl group in adjacent position to the olefinic double bond and which is substituted in addition by at least one carboxylate group not adjacent to the double bond. The novel compounds are used as starting for stabilizing halogen-containing polymers without influencing their transparency.
