    摘要： The present invention belongs to the field of polymer synthesis. In particular, the present invention relates to a method for the synthesis of regioregular polyesters, wherein the polymer ordered structure provides them with advantageous physical-chemical properties, starting from asymmetric diols. More particularly, by the method of the present invention it is possible to obtain regioregular polyesters having high glass transition temperatures Tg and crystalline properties. In the case in which the asymmetric diols are used in a pure enantiomeric form, with respect to the chiral carbon bound to the secondary hydroxyl, through the above-mentioned method it is possible to obtain regioregular and stereoregular polyesters, characterized by thermal and crystalline properties further ameliorative with respect to non-chiral regioregular polymers.

    摘要： A method of manufacturing an electrographic photoreceptor provided with a conductive substrate and a single-layered photosensitive layer is disclosed. The method includes: directly or indirectly applying a coating liquid for photosensitive layer formation onto the conductive substrate, the coating liquid containing a solvent, a charge generating agent, a binder resin, a hole transport material and an electron transport material; and removing part of the solvent to form the single-layered photosensitive layer. The solvent includes a first solvent as an alcohol with 1 to 3 carbon atoms and a second solvent as a solvent other than the first solvent. The binder resin includes a polyarylate resin as a polymerized product of monomers including a first monomer represented by General Formula (1) below and a second monomer represented by General Formula (2) below. The electron transport material includes a compound represented by General Formula (31), (32), (33) or (34) below.
