We report several kinds of interpenetrating polymer networks (IPNs) with nonlinear optical (NLO) properties. DMA spectra show that the two components of the IPNs have good compatibility with each other. The NLO materials have good optical transparency. The thermal stability of alignment was improved
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
