Abstract:
THE PRESENT INVENTION RELATES TO A PROCESS FOR RENDERING CELLULOSE-CONTAINING FIBROUS MATERIALS FLAMEPROOF, WHICH COMPRISES APPLYING TO SAID MATERIALS AN AQUEOUS PREPARATION CONTAINING PHOSPHORUS-CONTAINING N,N-DIMETHYLOLCARBOXYLIC ACID AMIDES. THE FLAMEPROOF FINISH IS RESISTANT TO WASHING AND DRY-CLEANING AND IMPROVES THE DRY CREASE ANGLE AND THE WET CREASE ANGLE OF THE FINISHED MATERIAL.
Abstract:
IN WHICH R denotes an alkyl radical with one to 18 carbon atoms and n denotes 1 or 2. These phosphonic acid dialkyl esters are used as antioxidants for plastics, especially for polypropylene, polyethylene and polyurethane, and rubber. The combined use of the phosphonic acid dialkyl esters with flameproofing agents, may increase the flameproofing action of the flameproofing agent. The use of the compounds according to the invention in combination with other antioxidants also may show advantageous effects.
The subject of the invention is phosphonic acid dialkyl esters of the formula

Phosphorus compounds are provided which correspond to the formula
WHEREIN EACH R is an alkyl, alkenyl or halogenalkyl radical, X and X'' each is a methyl radical or a hydrogen atom, Y and Y'' each is an alkyl radical or a hydrogen atom and A is an alkyl, halogenalkyl, hydroxyalkyl or a phenyl or benzyl group which both may be halogen substituted. The phosphorus compounds are manufactured from the corresponding phosphorus carboxylic acid amides and carbamates and formaldehyde. These compounds optionally together with a curable aminoplast precondensate are useful for flameproofing and creaseproofing of cellulosecontaining fiber materials.

The subject of the invention is a process for the manufacture of polycondensation products from hydroxymethylphosphonium compounds, characterised in that at least one anhydrous tetrakis(hydroxymethyl)-phosphonium salt or tetrakis(hydroxymethyl)phosphonium hydroxide is condensed with itself in an anhydrous medium, optionally using an acid catalyst and optionally in the presence of at least one inert organic solvent, at 100* to 150*C, preferably 120* to 150*C, the condensation being continued until 0.5 to 1.5 mols of water have been eliminated per 1 mol of phosphonium compound employed, free hydroxyl groups are, if appropriate, at least partially etherified with at least one alkanol with 1 to 4 carbon atoms, and that the salt of the polycondensation products are, where relevant, converted into the corresponding hydroxides. The polycondensation products are used for the flameproofing of organic fibre material, especially textiles. Appropriately, the procedure followed is that an aqueous preparation is applied to these materials which contains at least (1) a polycondensation product of the indicated type and (2) a polyfunctional compound, and that the material thus treated are dried and subjected to a heat treatment.
