There is provided herein an aluminum methyl methylphosphonate in crystalline form wherein 90% of the aluminum methyl methylphoshponate has a particle size of less than 10 microns, and wherein the aluminum methyl methylphosphonate is obtained by the process of reacting aluminum hydroxide with dimethyl methylphosphonate in the presence of a catalyst.

Metal phosphonate flame retardant and method producing thereof

There is provided herein a process for purifying bisphosphate comprising solvating a molten bisphosphate in a mixture of water and water miscible solvent; cooling the solution over a period and to a temperature that provides for crystallization of solid product; increasing the pH of the solution prior to, and/or during, and/or after the initiation of crystallization, and/or after crystallization, by the addition of a base; and after crystallization is complete, separating solid product from the solution; washing the separated solid product in the same and/or different mixture of water and water miscible solvent; and, washing the solid product which has been washed in the mixture with water.

Water miscible solvent based process for purifying a bisphosphate

An oligomeric phosphate or mixture of oligomeric phosphates having the general formula (I) wherein R, R, Rand Reach independently is aryl or alkaryl and n has an average value of from about 1.0 to about 2.0 and resin compositions containing the same.
