Zusammenfassung:	A toner resin suitable for being used in toner compositions or developer compositions for electrostatic imaging is prepared by polymerization of styrene and butadiene in the presence of a mixture of n-dodecyl mercaptan and t-dodecyl mercaptan. The toner resin has defined weight average and number average molecular weights and a defined polydispersity that provide an improved toner resin that can be attained without blending different copolymers while using conventional apparatus. Additionally, the toner resin can exhibit a suitable melt index and glass transition temperature.
