The polystyrenylphosphonous acid (PSPA) of low polymerization degree was prepared with one step reaction. The reaction mechanism was changed with different initiators. For the reaction with AIBN or BPO as the initiator, there are 2 or 3 series of radical reaction chains and 5 or 9 series of polystyrenyl products. The main products are PSPA without or with the fragment of the initiator H[CH(C₆H₅)-CH₂]n-PO₂H₂ and C₆H₅CO₂-[CH₂CH (C₆H₅)]n-PO₂H₂ respectively.
