Popis:	The new monomer N9-(b-methacryloyloxyethyl)-2-pyrimidyl-(p-benzyloxy- carbonyl)aminobenzenesulfonamide (MPBAS) (M1) is synthesized using sulfadiazine as parent compound. It could be homopolymerized and copolymerized with N-phenyl maleimide (NPMI) (M2) by radical mechanism using AIBN as initiator at 60 °C in dimethylformamide. The new monomer MPBAS and polymers were identified by IR, element analysis and 1 H NMR in detail. The monomer reactivity ratios in copolymer- ization were determined by YBR method, and r1 (MPBAS) 5 2.39 6 0.05, r2 (NPMI) 5 0.33 6 0.02. In the presence of ammonium formate, benzyloxycarbonyl groups could be broken fluently from MPBAS segments of copolymer by catalytic transfer hydroge- nation, and the copolymer with sulfadiazine side groups are recovered. © 2000 John Wiley
