Crystallization Behavior And Mechanical Properties Of Hyperbranched Polyesters In Toner Polymer Blends

Hyperbranched polymers with crystalline surface groups were synthesized and their crystallization behavior in the presence of primary toner polymers was investigated. In contrast to linear crystalline polymers, their crystallization is relatively unaffected by the presence or chemical structure of the primary toner polymer. They do not affect the glass transition temperature of the primary toner polymer and the polymer blends have lower storage modulus at low temperature but increased storage modulus at elevated temperature.
