THERMALLY REVERSIBLE ISOCYANATE-BASED POLYMERS |
摘要 |
Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. Aromatic polyimide, aromatic polycarbonate, polyarylsulfide, aromatic polyester with liquid crystal property, and polyarylimidazolidine oligomers are incorporated into the isocyanate or labile hydrogen compounds to give high-performance characteristics. Such thermally-reversible isocyanate-based polymer compositions with high-performance characteristics are useful, among other things, as finish surface coatings on composite materials such as polypropylene and polyethylene terephthalate. Novel phenolic-hydroxyl terminated polyarylsulfide and polyarylimidazolidine oligomers and their preparation are also described. |
