Patent ID: 8114467

Claim:
A polymer for forming a hydrophobic layer represented by Formula 1 below and having a weight average molecular weight of about 10,000 to about 500,000 g/mol: wherein Q 1 and Q 2 are each independently a linear or branched C 1 -C 10 alkylene group; R 1 and R 2 are each independently a substituent selected from the group consisting of —O—Z 1 , —O—C(O)—Z 2 , —O—Z 3 —C(O)—O—Z 4 and —O—C(O)—Z 5 —C(O)—O—Z 6 ; wherein Z 1 , Z 2 , Z 4 and Z 6 are each independently a linear or branched C 1 -C 30 alkyl group, wherein at least one hydrogen atom of the linear or branched C 1 -C 30 alkyl group is substituted with F; and Z 3 and Z 5 are each independently a linear or branched C 1 -C 20 alkylene group, wherein at least one hydrogen atom of the linear or branched C 1 -C 20 alkylene group is substituted by one selected from the group consisting of Cl, Br and I; R 3 to R 7 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, an amino group, a C 1 -C 10 alkyl group and a C 6 -C 12 aryl group; and the ratio of a:b+c is from 10:1 to 1:1,000.
