Patent ID: 8512596

Claim:
A composition, comprising: a liquid crystal polymer or oligomer having a terminal hydroxyl group; and a cross-linking agent comprising a bismaleimide compound, an epoxy resin or a combination thereof, wherein the liquid crystal polymer or oligomer is represented by Formula 1: wherein R 1 is represented by Formula 2: wherein X 1 and Y 1 are each independently selected from the group consisting of O, CO and NR″, in which R″ is independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted C 1 -C 20 alkyl group, and a substituted or unsubstituted C 6 -C 30 aryl group and Ar 1 comprises at least one divalent aromatic or alicyclic organic group selected from the group consisting of Formula 3: wherein at least one of the carbon atoms present in each of the aromatic and aliphatic rings is optionally replaced with a heteroatom independently selected from the group consisting of N, O, S and P, and each A 1 represents a single bond or is O, S, CO, SO, SO 2 or a divalent aliphatic or aromatic organic group, R 2 is represented by Formula 6: wherein X 2 and Y 2 are each independently selected from the group consisting of O, CO and NR″, and Ar 3 comprises at least one divalent aromatic or alicyclic organic group selected from the group consisting of Formula 7: wherein A 2 is N 2 , O, S, CO, SO, SO 2 or a divalent aliphatic or aromatic organic group, Z 1 and Z 2 are the same or different and are each independently an organic group comprising a hydroxyl, amine, carboxylic acid, acetyl or thiol group, with the proviso that at least one of Z 1 and Z 2 has a hydroxyl group, and m and n are each independently an integer from about 1 to about 100.
