Abstract

To increase the fatigue life of glassy polymers, such as polystyrene, without sig-nificantly changing other mechanical. properties, a lower modulus glassy material is incorporated to increase the rate of stress buildup in enhancing craze formation while presenting flaw sites for craze formation. The modified glassy materials are useful as electrostatographic toners, carrier coatings and photoconductors to increase their usable lifetime due to longer mechanical fatigue life.
