Abstract

Polymerization of 4,4′-bismaleimidediphenyl methane and N-phenylmaleimide was conducted in dimethyl formamide, catalyzed by nanocrystalline titania. The monomers and polymers involved were characterized with infrared spectroscopy, 1H-NMR, and 13C-NMR, respectively. The mechanism of the catalyzed polymerization was discussed as well. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 71: 665–669, 1999
