Interpenetrating polymer networks (IPNs) based on polyurethane and polyacylate-containing 4-(4'-nitrophenylazo) aniline chromophore groups were synthesized and characterized by infrared spectra, gel content and differential scanning calorimet y . Thin, transparent films of the IPNs were prepared by
## SYNOPSIS Radical copolymerization of N-(azo dye) maleimide or N-(substituted phenyl) maleimide and styrene were carried out using 2,2'-azobi~-isobutyronitrile as an initiator in THF at 60ยฐC. These copolymers exhibit high solubility in most of the organic solvents and excellent thermal stability
