Patent ID: 8859194

Claim:
A polymer compound comprising: 100 parts by mole of a repeating unit represented by Formula 1; 10 to 900 parts by mole of a repeating unit represented by Formula 2; and 10 to 900 parts by mole of a repeating unit represented by Formula 3, wherein the polymer compound has a weight average molecular weight of 1,000 to 100,000: wherein R 1 , R 3 , R 4 , R 5 , and R 6 are each independently a hydrogen atom, a fluorine atom, or a substituted or unsubstituted C 1 -C 20 alkyl group, R 2 is a substituted or unsubstituted C 1 -C 10 alkyl group or a substituted or unsubstituted C 1 -C 10 cyclic alkyl group, wherein at least one hydrogen atom of the C 1 -C 10 alkyl group and the C 1 -C 10 cyclic alkyl group is substituted with a group represented by Formula a, R 7 is a hydrogen atom or a substituted or unsubstituted C 1 -C 25 alkyl group, wherein R 8 is a hydrogen atom or a substituted or unsubstituted C 1 -C 25 alkyl group, R 9 is a single bond or a substituted or unsubstituted C 1 -C 10 alkylene or cycloalkylene group, and * indicates a binding site.
