thermally reversible polymers based on isocyanates.

OBTAINED polymer compositions thermally reversible by reacting isocyanate compounds HYDROGEN UNSTABLE AND FUNCTIONALITY. JOINING THE UNSTABLE COMPOUNDS isocyanate or HYDROGEN FOR HIGH PERFORMANCE CHARACTERISTICS, aromatic polyimide, aromatic polycarbonate, POLIARILSULFURO, aromatic polyester PROPERTY WITH LIQUID CRYSTAL AND POLIARILIMIDAZOLIDINA oligomers. TALES isocyanate-based polymer compositions thermally reversible, WITH HIGH PERFORMANCE CHARACTERISTICS ARE USEFUL, AMONG OTHER THINGS, AS FINISHING SURFACE COATINGS ON COMPOSITES, such as polyethylene terephthalate polypropylene and polyethylene. ALSO DESCRIBED oligomers POLIARILIMIDAZOLIDINA NEW AND FINISHED POLIARILSULFURO hydroxyl phenolic and its preparation.
