| 摘 要： | The polystyrenylphosphonous acid (PSPA) of low polymerization degress was prepared with one step reaction. The reaction mechanism was changed with different initiators. For the reaction with AIBN or BPO as the initiator, therer are 2 or 3 serives 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 HCH(C6H5)-CH2]n-PO2H2 and C6H5CO2-CH2CH(C6H5)]n-PO2H2 respectively.
