Patent number: 6503680Abstract: A process for the preparation of a latex polymer consistent with E/A (emulsion/aggregation/coalescence) toner manufacture. The process utilizes a standard (universal) latex composition and involves chain-transfer agent partitioning, emulsion polymerization that provides a latex polymer with a wide range of molecular properties. In particular, the process customizes a wide range Mw (weight average molecular weight) latex, without substantially varying the Mn (number average molecular weight) and hence, without substantially varying Tg (glass transition temperature) such that good toner performance is maintained. In a preferred process, a latex polymer is prepared by mixing a seed particle latex, generated by aqueous emulsion polymerization of a first portion of a monomer emulsion, with a second portion of the monomer emulsion and at least one chain-transfer agent.Type: GrantFiled: August 29, 2001Date of Patent: January 7, 2003Assignee: Xerox CorporationInventors: Allan K. Chen, George Liebermann, Tie Hwee Ng, Arthur Helbrecht, Emily L. Moore, Abdisamed Sheik-qasim, Patricia A. Burns, Nam S. Ro
