Title:
NOVEL FERROELECTRIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/135457
Kind Code:
A1
Abstract:
Disclosed are: a novel polymer material for organic ferroelectric materials; and an organic ferroelectric material. This polymer material is a polymer for organic ferroelectric materials, namely a (meth)acrylate polymer which contains, as a main monomer unit, one or more (meth)acrylates that contain, in a side chain, a saturated or unsaturated hydrocarbon skeleton that is bonded to an end of an oxycarbonyl group. The hydrocarbon skeleton has at least one hydrogen atom on a carbon atom that is in the β-position relative to the oxycarbonyl group; one or more electron-withdrawing groups selected from the group consisting of a halogen atom, a cyano group, an oxo group and a nitro group are bonded onto the β carbon atom and/or one or more carbon atoms closer to the end than the β carbon atom, thereby substituting the hydrogen atom; and the halogen atom is selected from among a fluorine atom and a chlorine atom.
