  • Patent number: 5688961
    Abstract: A method of manufacturing charge transporting materials which impart a charge transporting property to a polysiloxane resin, and which is soluble in the resin. The charge transporting material is an aromatic substituted tertiary amine with a plurality of aromatic groups, and a silyl group introduced via a hydrocarbon group, into at least one of the aromatic groups. The method is characterized by using an unsaturated aliphatic group bonded to an aromatic group which makes up the silicon-type charge transporting compound, or using a newly bonded unsaturated aliphatic group which is bonded to a silane in which the substituent for silicon is hydrogen or a hydrolyzable group. This is conducted in the presence of a platinum compound as catalyst by means of hydrosilylation. The silicon-type charge transporting material is then brought into contact with an adsorbent for the platinum compound, causing the platinum compound to be adsorbed onto the adsorbent.

    Abstract: A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an aldehyde accelerator. The aldehyde accelerators are especially useful for facilitating the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.
