Patent ID: 8232367

Claim:
A co-polymer compound comprising at least one selected from repeating units represented by Formulae 1, 3, 5, and 6, and a combination thereof, and a repeating unit represented by Formula 70 wherein Ar 1 is a tetravalent C 5 -C 24 arylene group or a tetravalent C 5 -C 24 heterocyclic ring, which is substituted or unsubstituted with at least one substituent selected from the group consisting of C 1 -C 10 alkyl, C 1 -C 10 alkoxy, C 1 -C 10 haloalkyl and C 1 -C 10 haloalkoxy, or two or more of which are fused together to form a condensation ring or covalently bonded to each other via a functional group selected from the group consisting of O, S, C(═O), CH(OH), S(═O) 2 , Si(CH 3 ) 2 , (CH 2 ) p (in which 1≦p≦10), (CF 2 ) q (in which 1≦q≦10), C(CH 3 ) 2 , C(CF 3 ) 2 and C(═O)NH; Ar 1 ' is a bivalent C 5 -C 24 arylene group or a bivalent C 5 -C 24 heterocyclic ring, which is substituted or unsubstituted with at least one substituent selected from the group consisting of C 1 -C 10 alkyl, C 1 -C 10 alkoxy, C 1 -C 10 haloalkyl and C 1 -C 10 haloalkoxy, or two or more of which are fused together to form a condensation ring or covalently bonded to each other via a functional group selected from the group consisting of O, S, C(═O), CH(OH), S(═O) 2 , Si(CH 3 ) 2 , (CH 2 ) p (in which 1≦p≦10), (CF 2 ) q (in which 1≦q≦10), C(CH 3 ) 2 , C(CF 3 ) 2 and C(═O)NH; Ar 2 is selected from the following compounds: wherein X is O, S, C(═O), CH(OH), S(═O) 2 , Si(CH 3 ) 2 , (CH 2 ) p (in which 1≦p≦10), (CF 2 ) q (in which 1≦q≦10), C(CH 3 ) 2 , C(CF 3 ) 2 , or C(═O)NH; W is O, S or C(═O); and Z 1 , Z 2 and Z 3 are identical to or different from each other and are O, N or S, and wherein the other end of Ar 2 is directly bonded to a nitrogen atom; Q is O, S, C(═O), CH(OH), S(═O) 2 , Si(CH 3 ) 2 , (CH 2 ) p (in which 1≦p≦10), (CF 2 ) q (in which 1≦q≦10), C(CH 3 ) 2 , C(CF 3 ) 2 , C(═O)NH, C(CH 3 )(CF 3 ), C 1 -C 6 alkyl-substituted phenyl or C 1 -C 6 haloalkyl-substituted phenyl; Y″ is —O or S; n is an integer from 10 to 400; and 1 is an integer from 10 to 400.
