Heat-resistent polyehter, curable polyether, and coating liquid for forming a polyether film |
| abstract |
A heat resistant polyether comprising a repeating unit represented by the following formula (1) and having a weight average molecular weight of polystyrene equivalent determined by GPC of 1000 to 50000, heat resistance to a temperature of 300 ° C. or higher, sufficient solubility in organic solvents, and low water absorption. And heat resistant polyethers having high adhesion to the substrate:n n n n n n n n n n [Wherein Ar represents a divalent organic group having an aromatic ring; R 1 to R 8 each independently represent a hydrogen atom or a substituted aryl group; When at least one of R 1 to R 8 is an aryl group which may be substituted, X is a direct bond or a hydrocarbon group having 1 to 20 carbon atoms, whereas when all of R 1 to R 8 are hydrogen atoms, X is represented by the following Chemical Formula 2 Is represented as:n n n [Formula 2]n n n -CR 9 (R) 10- n n n (Wherein R 9 and R 10 each independently represent an aryl group which may be substituted) |
