Syntheses and reaction of functional polymers. XXXIX. Syntheses of poly‐N‐acrylyl‐2‐oxazolidone and complex formation of phenol, methyl bromide and halogens with polymers containing 2‐oxazolidone groups

N‐Acrylyl‐2‐oxazolidone was synthesized by the reaction of N‐sodium‐2‐oxazolidone with acrylyl chloride. N‐Acrylyl‐2‐oxazolidone (M1) was polymerized and copolymerized with styrene (M2) by free radical initiator. The monomer reactivity ratios, r1 (= 0.24) and r2 (= 1.35) were determined by the method of FINEMAN and ROSS, and the ALFREY‐PRICE Q (= 0.37) and e (= 0.367) values were estimated. These polymers were soluble in dimethylformamide and dimethylsulfoxide, but insoluble in common organic solvents. They formed complexes with phenol, halogens and methyl bromide. Further, the bonding characters in the complexes of various polymers containing 2‐oxazolidone moiety and phenols, methyl bromide and halogens were investigated.
