The composition of a homopolymer of (phosphonyl) aromatic diester compound using a catalyst and a glycol is provided. Further, the composition of a copolymer of the (phosphonyl) aromatic diester compound using a catalyst, a glycol and a second diester is provided. These polymers find application as flame retardants during synthesis of various polymeric materials.

The composition of a (phosphonyl) aromatic compound represented by (I) is provided. In this composition, R1(a) and R1(b) are each independently H, CnH2n+1, phenyl or benzyl; R2(a) and R2(b) are each independently H, CnH2n+1, phenyl or benzyl with the proviso that no more than one R2(a) and no more than one R2(b) can be phenyl or benzyl; R3(a) and R3(b) are each independently CnH2n+1, phenyl or benzyl; and, n is an integer of 1 - 10; and p is an integer of 1 - 10. The disclosed composition can find utility in improving flame retardancy of polyesters, aramids and nylons.
