Crystalline Hyperbranched Polyesters for Toners

摘要

Fusing and hot offset performance are dependent on the rheological properties of the toner. In this study, the influence of crystalline hyperbranched polymers on these properties is investigated. Toner resin blends containing these polymers exhibit a low melt viscosity for improved fusing and increased high temperature storage modulus for good hot offset resistance. In contrast to linear resins, these polymers exhibit rapid crystallization behavior and do not plasticize the primary toner resin.
