摘要
The phenoxyphosphazene compound of the present invention is prepared by treating a phenoxyphosphazene compound with (a) at least one adsorbent selected from activated carbon, silica gel, activated alumina, activated clay, synthetic zeolite and macromolecular adsorbents, (b) at least one reagent selected from metal hydrides, hydrazine, hypochlorites, thiosulfates, dialkyl sulfuric acids, ortho esters, diazoalkanes, lactones, alkanesultones, epoxy compounds and hydrogen peroxide or (c) both the adsorbent and reagent. Incorporation of the phenoxyphosphazene compound prepared by the process of the invention into a synthetic resin achives the following advantages: the synthetic resin can be prevented from discoloration; when the resultant resin composition is stored for a long time, the properties of the synthetic resin, such as heat resistance, weatherability, resistance to discoloration and chemical resistance are not deteriorated; and the resin composition gives a resin composition molded article excellent in properties such as flame retardancy, thermal stability, and moldability.
