A new type of maleimide monomer, N-(4-acetylphenyl)maleimide (NAPMI), was synthesized. The oxime, carbazone, and thiosemicarbazone derivatives of NAPMI were prepared with hydroxylamine hydrochloride, semicarbazide hydrochloride, and thiosemicarbazide hydrochloride, respectively. Radical homopolymerization of NAPMI and its derivatives were prepared at 60 °C in dimethyl sulfoxide solution with azobisisobutyronitrile as an initiator. The monomers and theirs homopolymers were characterized with Fourier transform infrared and NMR techniques. The glass-transition temperatures, thermal stability, and ultraviolet stability of the polymers are compared. The activation energies of the thermal degradation of polymers were calculated by the Kissinger method. The antibacterial and antifungal effects of the monomers and polymers were also investigated on various bacteria and fungi. © 2003 Wiley Periodicals, Inc.

N-（4-乙酰苯基）马来酰亚胺及其肟，碳巴酮，硫代半碳酰胺衍生物及其聚合物的合成，表征和生物学活性

新型马来酰亚胺单体N合成了-（4-乙酰基苯基）马来酰亚胺（NAPMI）。分别用盐酸羟胺，盐酸氨基脲和盐酸氨基脲制备了NAPMI的肟，氨基甲酸酯和硫半脲衍生物。NAPMI及其衍生物的自由基均聚反应是在60°C，以偶氮二异丁腈为引发剂，在二甲基亚砜溶液中制备的。用傅里叶变换红外和核磁共振技术对单体及其均聚物进行表征。比较了聚合物的玻璃化转变温度，热稳定性和紫外线稳定性。聚合物热降解的活化能通过基辛格方法计算。还研究了单体和聚合物对各种细菌和真菌的抗菌和抗真菌作用。
