Abstract

Crosslinked polymers can have gel and non-gel components which can be changed by shearing in a melt processor such as an extruder. The structure of the gel or the crosslinked portion after the toner is made appears to have a significant effect on gloss. As an example, reactive extruded polyesters processed at different temperatures or in different extruders gave different gloss. Lower process temperatures resulted in higher viscosity and lower gloss in the toner image, whereas, higher process temperatures gave rise to lower viscosity and higher gloss in the toner image. Gloss can therefore be controlled by toner processing in a shear mixing device.
