  • Semiconducting component for electrographic device
    Patent number: 10158082
    Abstract: A semiconducting component for an electrographic device, comprising a crosslinked body obtained by crosslinking a copolymer containing 9.9 to 39.9% by mole of structural units (a) originating from an epihalohydrin, 60 to 90% by mole of structural units (b) originating from an alkylene oxide, and 0.1 to 10% by mole of structural units (c) originating from a cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group with use of reactivity of the structural units originating from the cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group.
