発明の名称 (英語) Hydrophilic polyamide or polyimide NEW
発明の概要(英語) Provided are a hydrophilic polyamide and polyimide retaining characteristics particular to polyamides and polyimides, such as heat resistance. A polymeric compound is provided having a repeating unit represented by the following formula (1):wherein M1and M2each 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 M1and M2are not a hydrogen atom at the same time; X1and X2represent an organic group; m and n each independently represent the number of substituents; Z1represents a hydrogen atom or an optionally substituted carbonyl group; Z2represents an optionally substituted hydrocarbon group; Z3represents a hydrogen atom or an optionally substituted carbonyl group; and when Z1or Z3is an optionally substituted carbonyl group, they optionally form a ring structure together with Z2, each independently.

従来技術、競合技術の概要(英語) BACKGROUND ART
A polymeric material such as polyimide or a polyamide of electrical engineering, electronics and aerospace engineering and the like are widely used in various fields or the high performance plastic is, demand is quite large. Heretofore, such polymer materials to be synthesized in almost all petroleum raw materials can occur due to the low demand enlargement of the opposite direction from the digestion.
On the other hand, using a raw material of natural origin bio plastics polymer material, unlike long biofuel carbon dioxide immobilization is expected for practical use is low is thought to contribute significantly to the digestion but are not limited to, the production cost increases and this has become a major issue of the present invention. Alternatively to the point of view, the cost is increased even in the case of using a biological molecule such as a super engineering plastic material having a high added value if, cost effect can be also unsatisfactory, socially possess the potential to be widely spreading.
According to this aspect, the present inventors have found in a naturally occurring 4-amino cinnamic acid dimers of the starting material (4 field aminocinnamic acid) in the preparation of polyamides or polyimides, the polyamides or polyimides show excellent heat resistance, high tensile strength, higher transparency and, in a broad field of polymer materials and have been found to be useful as previously reported (patent documents 1 and 2) was.
In addition, the polyimide having rigid skeletons and thus poorly soluble in water and an organic solvent having a low moldability with a drawback that the present invention. In this, the development of the polyimide to improve formability and reached the present invention (patent document 3 and 4).
