抄録

New vinyl aromatic compound polymers containing 2-chloroacetamidomethyl groups have been prepared from the corresponding polymers by amidomethylation with N-methylol-2-chloroacetamide (NMCA). The reaction proceeds in nitrobenzene or nitropropane in the presence of sulfuric acid as catalyst at temperature of 10 to 25^°C. When 1.1 molar or less than 0.3 molar of NMCA to a molar of polystyrene is used, a soluble polymer is obtained. From poly(4-methylstyrene) or poly(4-tert-butylstyrene), soluble polymers containing 2-chloro-acetamidomethyl group are also obtained by the same reaction. ¹H NMR, ¹³C NMR, FT-IR spectroscopy, and elemental analysis identifies the structures. These polymers are soluble in DMF or chloroform. In the case of poly(4-methylstyrene), NMR analysis shows that meta substituted product is exclusively obtained, although there are two possibilities of ortho- and meta-substituted products.
