The invention also relates to an electrophotographic printing machine, a developing apparatus, and a coated transport member, an intermediate transfer belt, and a hybrid compliant photoreceptor comprising a composition of the invention.Type: GrantFiled: October 18, 1994Date of Patent: November 10, 1998Assignee: Xerox CorporationInventors: Joseph Mort, Bing R. Hsieh, Mary A. Machonkin, Joseph Mammino, John F. Yanus

Patent number: 5739176Abstract: A biodegradable polymer is provided for use in providing syringeable, in-situ forming, solid biodegradable implants for animals. The polymer is placed into the animal in liquid form and cures to form the implant in-situ. A thermoplastic system to form said implant comprises the steps of dissolving a non-reactive polymer in biocompatible solvent to form a liquid, placing the liquid within the animal, and allowing the solvent to dissipate to produce the implant. An alternative, thermosetting system comprises mixing together effective amounts of a liquid acrylic ester terminated, biodegradable prepolymer and a curing agent, placing the liquid mixture within an animal and allowing the prepolymer to cure to form the implant. Both systems provide a syringeable, solid biodegradable delivery system by the addition of an effective level of biologically active agent to the liquid before injection into the body.Type: GrantFiled: March 18, 1994Date of Patent: April 14, 1998Assignee: Atrix Laboratories, Inc.Inventors: Richard L. Dunn, James P. English, Donald R. Cowsar, David D. Vanderbilt
