Hydrophilic polyamide or polyimide
|
| 発明の概要（英語） | wherein M1 and M2 each independently represent any one selected from the group consisting of a hydrogen atom, a monovalent metal atom, an alkaline earth metal atom and an ammonium ion, provided that M1 and M2 are not a hydrogen atom at the same time; X1 and X2 represent an organic group; m and n each independently represent the number of substituents; Z1 represents a hydrogen atom or an optionally substituted carbonyl group; Z2 represents an optionally substituted hydrocarbon group; Z3 represents a hydrogen atom or an optionally substituted carbonyl group; and when Z1 or Z3 is an optionally substituted carbonyl group, they optionally form a ring structure together with Z2, each independently. |

BACKGROUND ART Polymeric materials such as polyimides and polyamides are high-performance plastics widely used in a variety of fields such as electrical engineering, electronic engineering and space engineering, and needs for these materials are extremely high. Conventionally, almost all of these polymeric materials have been synthesized from petroleum-derived raw materials, and therefore, expansion of demand to them runs counter to reduction of carbon emissions. On the other hand, bioplastics, which are polymeric materials using naturally derived raw materials, are, not like biofuels, expected to fix carbon dioxide for a long period of time. It is believed that practical application of bioplastics largely contributes to reduction of carbon emissions; however, there has been a big problem that the production cost therefor is high. From a viewpoint different form this, even in the case where highly expensive biomolecules are used, as long as those materials have high added value like super engineering plastics, they can also be satisfactory in terms of cost effectiveness, and have a potentiality of spreading widely to the society. From such a viewpoint, the present inventors have produced a polyamide or polyimide using a dimer of naturally derived 4-aminocinnamic acid as the raw material, and have found and previously reported that such polyamide or polyimide exhibits excellent heat resistance, high tensile strength and high transparency, and is useful as a polymeric material in a wide variety of fields (Patent Literatures 1 and 2). In addition, because polyimides have a rigid backbone, they have a disadvantage of exhibiting poor solubility to water and organic solvents and having low formability. Accordingly, development of a polyimide with improved formability has been carried out (Patent Literatures 3 and 4). |
