Styrene - maleic anhydride Synthesis and Investigation of static photographic properties

Spectrum (solid line P.s.MAn, dashed line Vylor-200) 1995 No. 2 Imaging Science and Practice of 41.3 Results and Discussion (1) electrostatic photographic P. S. MAn resin can be used with low chain transfer constant of benzene as solvent free radical polymerization, initiator benzoyl peroxide can be used (BP0), in order to avoid ionic polymerization or emulsion of water and electrolytes into the insulation caused by decline. While styrene monomer and solvent is also subject to strict refined. (2) P. S. S and the resin is MAn MAn alternating monomer composition, changes in the reactant ratio of two substances had little effect on the product down, mainly because the two carbon-carbon double bonds (c = c) the pull of the differences over large, the reaction shown by the reactivity ratio r |,[link widoczny dla zalogowanych], r: are close to zero 0. (3) P. & MAn resin surface potential and dark attenuation by the vacuum drying treatment greatly improved. Its electrical properties can be seen with the trace moisture are closely related. Polymer may also be the primary key on the Open button to the formation of a small amount of carboxylic acid anhydride has a relationship. These substances may be under strong electric field to create a current carrier, or the formation of conductive channels to lower Vs, ie (dV / dt) v ~ ll. (4) under the same conditions in the charge, with £ a cuPc and P. DEH doped S. MAn of the sharp decline in the ability to accept charge, leading to surface saturation potential Vm decreased to less than 40V, but the samples doped with TNF the Vm and (dV / dt) v. Compared with the undoped sample remained unchanged. P. eliminated by UV S. DEH MAn and dopant compounds to generate new or complete electron transfer complex may cause the phenomenon may be due to P. S. MAn anhydride groups due to the strong electron withdrawing effect, c atoms with partial positive charge tends to make it into a good electron acceptor (Acceptor), while the £-cuPc by the DEH and the structure can be seen where N atom has a lone pair electron, which is an electron donor (Donor), the electron donor and acceptor molecules attract the positive and negative charges. Caused by partial transfer of charge between the intensity to form a kind of directional alignment of polar molecules Q and electronic transfer complex (cTc) some of the same structure. And this structure under the action of the electric field strength. Orientation of the charge transfer can occur so that insulation performance declined significantly Erzhi For TNF, because its structure in three strong electron withdrawing group (a NO) in the presence of the TNF receptor showed strong character, not with P. same nature S. MAn the formation of the structure, so no significant changes in its insulation properties. However,[link widoczny dla zalogowanych], DEH, and TNF on the P. & MAn doping the great differences shown by the real causes and the mechanism remains to be further explored. 4 Conclusion and resin monomers in the appropriate treatment, with a radical solution polymerization of styrene can be synthesized with maleic anhydride ratio of 1; l of P. S. MAn, showed itself a very good insulation, satisfy the basic requirements for electrostatic photography when used as an organic photoconductive material (CGM,[link widoczny dla zalogowanych], CTM) in the dispersion medium, the resulting charge to accept the light conductor dark decay speed performance and static photographic and optical properties of materials are closely related to electron affinity. Resin doped with TNF, the basic electrical properties of undoped resin with the same, the Bank of resin doped with DEH basic charge does not power on, after doping with TNF P. S. MAn light guide film composition could be a good electron transport organic photoconductor.
