There is provided herein a method of making hydroxymethylphosphonate comprising reacting paraformaldehyde, at least one dialkyl phosphite and at least one trialkyl phosphite, in the presence of at least one amine catalyst.

Method of making hydroxymethylphosphonate, polyurethane foam-forming compositions, polyurethane foam and articles made therefrom

A process is provided for the production of diaryl alkyl phosphonate by the reaction of triaryl phosphate with dialkyl alkyl phosphonate in the presence of alkali metal iodide catalyst; and, optionally, the diaryl alkyl phosphonate is reacted in situ with aromatic diol and, optionally, with at least one branching monomer, in the absence of other or further added catalyst to provide oligomeric and/or polymeric phosphonate products.

Process for preparing diaryl alkylphosphonates and oligomeric/polymeric derivatives thereof

Epoxy resins that are suitable for forming epoxy laminates that meet a UL-94 rating of V-0 comprise a hydroxy-terminated oligomeric phosphonate comprising the repeating structure &#x2014;OP(&#x2550;O)(R)OArylene-, where R is alkyl, as a flame retardant.

Oligomeric, hydroxy-terminated phosphonates

A phosphate ester composition of low acidity achieved by treating the phosphate ester of high acidity with an oxetane compound. The phosphate ester can be represented by the formula (I), where Ar is an aryl or alkaryl group, R is an arylene or alkylene group, and n can range from to 0 to about 5. 

Low acidity phosphate esters

An aqueous finishing composition for cellulose-containing materials, comprising a hydroxyalkyl-functional organophosphorus flame retardant (which contains a substantially non-volatile component at the curing temperature) and a non-formaldehyde cross-linking agent (such as a polycarboxylic acid cross-linking agent), and the materials treated with such a composition. Optional ingredients for the aqueous finishing composition include a cross-linking catalyst and/or an inexpensive saturated alpha-hydroxy polycarboxylic acid such as citric acid (partial replacement of a more expensive preferred polycarboxylic acid will reduce finishing costs).

Formaldehyde-free flame retardant treatment for cellulose-containing materials

A metal article is protected from corrosion under prolonged exposure to normal ambient atmospheric conditions which cause such corrosion by coating the metal article, optionally in the presence of an adherent organic resinous coating, which comprises treating the metal with an effective amount of effective amount of one or more hydrocarbyl-substituted sulfonyl amido diphenylamine compounds for the corrosion protection of the metal article. These compound(s) are of the formula p-(R--SO.sub.2 --NH--C.sub.6 H.sub.4 --NH)--C.sub.6 H.sub.5, where R is a substituted or unsubstituted hydrocarbyl group selected from the group consisting of alkyl, aryl, alkaryl, aralkyl, alkenyl, and cycloalkyl. A particularly preferred compound is p-(p-toluene sulfonyl amido)-diphenylamine.

Corrosion protection of metals using diphenylamine compound(s)

A flame retardant polyolefin composition comprises at least about 25% by weight magnesium hydroxide and, preferably, at least about 30%, at least about 5% by weight melamine and, preferably, at least about 20%, and at least about 0.5% by weight novolac and, preferably at least about 1%.

Polyolefin composition comprising magnesium hydroxide, melamine and

A metal article is protected from corrosion under prolonged exposure to normal ambient atmospheric conditions which cause such corrosion by coating the metal article with an adherent organic coating which does not exude corrosive acid, which comprises an effective amount of an aromatic amine compound containing a p-phenylenediamine moiety which is not an epoxy crosslinking agent but which is capable of being oxidized in air, an air oxidation product thereof, or a mixture of the amine and air oxidation product for corrosion protection of the metal article, before the coated metal article is placed in contact with such atmospheric conditions which cause such corrosion.
