The polystyrenylphosphonous acid was synthesized by free radical reaction for the first time,and which was characterized by IR and MS. According to the MS data,it is found that the free radical reaction mechanism were different. between two initiators. For the reaction with 2,2′-azobisisobutyronitrile as initiator,there are two series of radical reaction chains, five series of polystyrenyl compounds among them and the main product is the polystyrenylphosphonous acid without the fragment of the initiator H[CH(C 6H 5)CH 2] n-PO 2H 2. For the reaction with benzoyl peroxide as initiator,there are three series of radical reaction chains, nine series of polystyrenyl compounds in which the main product is the polystyrenylphosphonous acid with the fragment of the initiator C 6H 5CO 2-[CH 2CH (C 6H 5)] n-PO 2H 2.
