Polyamide acid and resin composition containing same |
| abstract |
It is possible to provide a polyamic acid which can lower the viscosity when it is used as a varnish and also has excellent mechanical properties after firing and that the polyamic acid having a mechanical property similar to that of an acid anhydride of an acid dianhydride and an amino group of a polyamine compound or a diamine compound The object of the coating film after firing is to show good mechanical properties. Is solved by a polyamic acid containing a structure represented by the following formula (1). [In the formula (1),? Represents oxygen or sulfur, and W represents an electron-withdrawing group. R 11 and R 12 each independently represent hydrogen or a hydrocarbon group having 1 to 10 carbon atoms, |
