Abstract

A novel polymerizable compound of the present invention is represented by the following general formula (I). Due to the presence of a reactive phenolic hydroxyl group at the end of the molecule, it can be reacted easily with various functional compounds and is useful as a monomer and an intermediate for various functional materials, especially as an intermediate for a polymerizable liquid crystal material. wherein R 1 is a hydrogen atom, a methyl group or a halogen atom; R 2 is an optionally substituted alkyl group having 1 to 6 carbon atoms, an optionally substituted alkoxy group having 1 to 6 carbon atoms, a halogen atom or a cyano group; an alkylene group of each of the alkyl and the alkoxy group may be interrupted by an unsaturated bond, an ether bond, a thioether bond or an ester bond; n is an integer from 0 to 14; and m is 0 or 1.

Claims (3)

1. A novel polymerizable compound represented by the following general formula (I),

wherein R 1 is a hydrogen atom, a methyl group or a halogen atom; R 2 is an optionally substituted alkyl group having 1 to 6 carbon atoms, an optionally substituted alkoxy group having 1 to 6 carbon atoms, a halogen atom or a cyano group; an alkylene group of each of the alkyl and the alkoxy group may be interrupted by an unsaturated bond, an ether bond, a thioether bond or an ester bond; n is an integer from 0 to 14; and m is 0 or 1.

2. The novel polymerizable compound according to claim 1 , which is a synthetic intermediate for a polymerizable liquid crystal compound.
