    摘要: The composition of a (phosphonyl) aromatic compound represented by (I) is provided. In this composition, R
    1 (a) and R
    1 (b) are each independently H, C
    n H
    2n+1 , phenyl or benzyl; R
    2 (a) and R
    2 (b) are each independently H, C
    n H
    2n+1 , phenyl or benzyl with the proviso that no more than one R
    2(a) and no more than one R
    2(b) can be phenyl or benzyl; R
    3 (a) and R
    3 (b) are each independently C
    n H
    2n+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.
