Abstract

Modified polyphosphonitrides are obtained by heating a polyphosphonitrilic chloride with a polyhydroxy aromatic compound under anhydrous conditions. The aromatic compound may be a partial ester with boric acid, with an inorganic phosphoric acid or a polyfunctional chlorine derivative thereof, or with phosphorus trichloride, which partial ester contains free phenolic hydroxy groups and which may be formed in situ. The preferred polyphosphonitrilic chlorides are of low molecular weight and are crystalline or liquid. If they are reacted with more than 75 per cent of a dihydroxy benzene or equivalent of other polyhydroxy benzene, the reaction is preferably not taken to completion, and the products are reactive with an aldehyde such as formaldehyde, acetaldehyde, metaldehyde, furfaraldehyde and paraformaldehyde, and with hexamethylenetetramine, trishydroxymethyl phosphine oxide, tetrakis-hydroxymethyl phosphonium chloride and trioxane, to give hard or rubbery cured resins. With less than 75 per cent of dihydroxy compound, the reaction may be taken to completion yielding products which are not reactive to aldehydes. A portion of the polyhydroxy compound may be replaced by a monohydroxy aromatic compound. Examples of polyhydroxy compounds are hydroquinone, resorcinol, toluhydroquinone, diphenylolpropane, phloroglucinol, pyrogallic acid, di-o-cresylolpropane, catechol and commercial mixed dihydric phenols. The reaction may be effected by heating the reactants alone or in a solvent such as tetrachloroethane, methyl ethyl ketone, xylene and butanol. The products may be mixed with fillers, e.g. asbestos fibres, alumina, powdered graphite, powdered mica and silica, to give moulding compositions, or dissolved in solvents, e.g. ethanol or methyl ethyl ketone, to which tricresyl phosphate may be added, and applied as coating compositions for metals. The products may also be used in laminates, abrasive elements, adhesives and impregnating compositions and for fireproofing. Specifications 788,785 and 807,851 are referred to.
