    摘要： Methods for polymerization of phosphaalkenes using initiators are provided. Also provided are polymers and co-polymers in which the polymer backbone contains tracts of carbon and phosphorous atoms in approximately equimolar amounts. C—P bonds in the polymers of this invention may be predominantly in a head-to-tail arrangement or mixed arrangements. Co-polymers may comprise polyolefin monomer units.

    摘要： 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.
