摘要:
A process or method for forming silane esters that is substantially free of oligomers. The process includes reacting an anhydrous salt of a carboxylic acid with a silane in a two phase reaction system. The silane comprises a halo-alkyl substituent. The two phase reaction system comprises a first solvent and a second solvent, wherein the second solvent is a solvent that is substantially non-miscible in the first solvent. An imaging member produced utilizing the silane esters so formed are also produced herein.
