| titleOfInvention | Novel high heat-resistant polyamideimide resin having a cyclohexylidene moiety and the preparation method thereof |
| abstract | The present invention relates to a novel high heat-resistant soluble polyamideimide resin and a method for preparing the same, and more particularly, to an aromatic diamine having a trimellitic acid chloride and an aliphatic ring substituted with alkyl groups of various structures. It relates to a new type of polyamideimide resin having excellent solubility as well as heat resistance and a method for producing the same.n n n n n n n n Wherein R is hydrogen, 4-methyl, 4-ethyl, 4-tert-butyl, 4-amyl, 4-phenyl or 3,3,5-trimethyl. That is, a novel poly having excellent heat resistance and excellent dissolution properties by reacting with trimellitic acid chloride by using one or two or more diamines selected from the diamines of the above formula as monomers instead of the aromatic diamines used in the preparation of conventional polyamideimide resins. As the amidimide resin was prepared, such polymers exhibit a glass transition temperature of 300 to 400 ° C., and the solubility increases as the volume of the alkyl group increases, so that even at room temperature in various organic solvents, especially low absorbing solvents such as cyclohexanone, etc. Demonstrates excellent dissolution properties that dissolve easily. |
