    Abstract: There is provided herein a process for the preparation of aluminum salts of phosphonic acid esters by reacting phosphonic acid diesters with aluminum hydroxide in the presence of a catalyst. The catalyst is selected from the group consisting of a phase transfer catalyst, a thermally stable tertiary amine having a boiling point higher than about 140°C, a thermally stable tertiary phosphine having a boiling point higher than 140°C and combinations thereof. The aluminum phosphonates prepared can be used for making flame retarded thermoplastic polymers.
