| 摘 要： | Organophosphorus chemistry plays an important role in chemical engineering, pesticide, medicine and catalysis1,2. In recent years, after extensive research and widespread application, synthesis and preparation of new organophosphorus compounds have attracted increasing research interest. Polystyrene is a very important and versatile matrix or precursor of various kinds of functional polymer. Usually, introducing of phosphonic PO3H2 or phosphinic PO2H2 group into polystyrene matrix through…

| Abstract: | 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 HCH(C6H5)-CH2]n-PO2H2 and C6H5CO2-CH2CH (C6H5)]n-PO2H2 respectively. |
