The present invention relates to a compound represented by Formula (1) and a polymer obtained using the compound:
wherein R1 is phenyl which may have substituents, Q1 is hydrogen, halogen, alkyl having 1 to 10 carbon atoms, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclohexenyl or phenyl in which optional hydrogen may be replaced by halogen or alkyl having 1 to 5 carbon atoms,
and Q2 is a group represented by Formula (2) wherein the code < represents a bonding point with silicon, l, m, n and p are independently 0, 1, 2 or 3, A1 to A4 are independently a single bond, 1,4-cyclohexylene, 1,4-cyclohexenylene, a condensed ring group having 6 to 10 carbon atoms which is a divalent group, or 1,4-phenylene, Z0 to Z3 are independently a single bond, —CH═CR—, —C≡C—, —COO—, —OCO—, or alkylene having 1 to 20 carbon atoms, and Z4 is a single bond, —CH═CH—, —C≡C—, —COO—, —OCO—, or alkylene having 1 to 20 carbon atoms. And Y1 in Formula (1) is the group defined in Claim 1.
