Document Type and Number:
Japanese Patent JP7381454
Kind Code:
B2
Abstract:
A polymer for organic ferroelectric materials and an organic ferroelectric materials are disclosed. The polymer is a (meth)acrylic polymer, wherein the polymer comprises one or more (meth)acrylates as main monomer units and one or more (meth)acrylic monomers other than the main monomer units, wherein the main monomer units are (meth)acrylate monomer units having in the side chain thereof a saturated or unsaturated hydrocarbon skeleton linked to the distal end of the oxycarbonyl group, wherein the hydrocarbon skeleton has a hydrogen atom on the β-carbon atom relative to the oxycarbonyl group, and one or more electron withdrawing groups selected from halogen atom, cyano group, oxo group, and nitro group, that bind to the β-carbon atom and/or to one or more carbon atoms distal thereto, substituting for hydrogen atoms thereon, wherein the proportion of the main monomer units is less than 80 mol% of the total (meth)acrylic monomer units.
