First claim

Opening claim text (preview).

What is claimed is: 1. A polyimide precursor composition, comprising an amic acid ester oligomer of formula (I): wherein: r is an integer ranging from 1 to 200; Each R x is independently H, C 1 -C 14 alkyl or a moiety bearing an ethylenic-ally unsaturated group; Each R is independently C 1 -C 14 alkyl, C 6 -C 14 aryl or aralkyl, or a moiety hearing an ethylenically unsaturated group; Each G is independently a tetravalent organic group; and Each F is independently a divalent organic group, wherein based on the total moles of the divalent organic groups P present in the composition, about 0.5 mol % to about 25 mol % of the divalent organic group P is a divalent organic group that is capable of forming a coordinate bond with a metal ion, wherein the divalent organic group that is capable of forming a coordinate bond with a metal ion is selected from the group consisting of: and (vi) a combination of radicals (i)-(v), wherein: D is a bond, —NH—, —S—, —O—, phenylene or E is 5 or 6-membered nitrogen-containing heterocyclyl F is phenylene or and X is —NH—, —S— or —O—. 2. The polyimide precursor composition according to claim 1 , wherein r is an integer ranging from 5 to 150. 3. The polyimide precursor composition according to claim 1 , wherein the divalent organic group that is capable of forming a coordinate bond with a metal ion is selected from: or a combination thereof wherein X is —NH—, —S— or —O—. 4. The polyimide precursor composition according to claim 1 , wherein based on the total moles of the divalent organic-groups P present in the composition, about 1 mol % to about 15 mol % of the divalent organic group P is an divalent organic group that is capable of forming a coordinate bond with a metal ion. 5. The polyimide precursor composition according to claim 1 , wherein tire remaining divalent organic groups P are each independently a divalent aromatic group or divalent heterocyclic-group other than tire radicals listed in (i) to (v) and are selected horn the group consisting of: and a combination thereof, wherein each R 9 is independently H, C 1 -C 4 alkyl, C 1 -C 4 perfluoroalkyl, C 1 -C 4 alkoxyl or halogen; each a is independently an integer from 0 to 4; each b is independently an integer from 0 to 4; R 10 is a covalent bond, or selected from the group consisting of: —O—, —S—, —CH 2 —, —S(O) 2 —, —C(CF 3 ) 2 —, —C(CH 3 ) 2 —, wherein c and d are each independently an integer from 1 to 20, R 12 is —S(O) 2 —, a covalent bond, C 1 -C 4 alkylene or C 1 -C 4 perfluoroalkylene. 6. The polyimide precursor composition according to claim 1 , wherein G is selected from the group consisting of: and a combination thereof, wherein each X′ is independently H, halogen, C 1 -C 4 perfluoroalkyl, C 1 -C 4 alkyl; and A and B are independently, at each occurrence, a covalent bond, C 1 -C 4 alkylene unsubstituted or substituted with one or more radicals selected from C 1 -C 4 alkyl, C 1 -C 4 perfluoroalkylene, C 1 -C 4 alkoxylene, silylene, —O—, —S—, —C(O)—, —OC(O), —S(O) 2 —, —C(═O)O—(C 1 -C 4 alkylene)-OC(═O)—, phenylene, biphenylene or wherein K is —O—, —S(O) 2 —, C 1 -C 4 alkylene or C 1 -C 4 perfluoroalkylene. 7. The polyimide precursor composition according to claim 1 , wherein each R is independently is selected from the group consisting of: and a combination thereof. 8. The polyimide precursor composition according to claim 1 , farther comprising a cyclization promoter having the following formula: wherein: R 1 and R 2 are the same or different and are each independently H, C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, or C 1 -C 6 alkyl substituted with one or more C 6 -C 14 aryl, R A is C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, C 1 -C 8 alkoxy unsubstituted or substituted with one or more C 6 -C 14 aryl, or —NR E R F ; R B , R C , R D , R E and R F are the same or different, and are each independently H, C 1 -C 14 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl; R 3 , R 4 and R 5 are the same or different, and are each independently II, straight or branched C 1 -C 6 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, straight or branched C 1 -C 6 hydroxyalkyl, straight or branched C 1 -C 6 cyanoalkyl, or C 6 -C 14 aryl; and Y θ is an anionic group. 9. The polyimide precursor composition according to claim 1 , wherein the amic acid ester oligomer is in an amount of about 10 wt % to about 70 wt %, based on the total weight of the polyimide precursor composition. 10. The polyimide precursor composition according to claim 8 , herein the cyclization promoter is in an amount of about 0.1 parts by weight to about 2 parts by weight, based on 100 parts by weight of the amic acid ester oligomer of formula (I). 11. The polyimide precursor composition according to claim 1 , wherein the divalent organic group that is capable of forming a coordinate bond with a metal ion is selected horn: or a combination thereof. 12. A polyimide prepared from the precursor composition according to claim 1 .
