Abstract
(EN)
Described herein are polymerblends having improved impact performance and outstanding chemical resistance. The polymerblends include at least one semi- aromatic polyester polymer, at least one poly(phenyl sulfone) polymer, and at least one impact modifier. In some embodiments, the polymerblends can optionally include one or more aromatic polycarbonate polymers, one or more poly(aryl ether sulfone) polymers and one or more additives. In some embodiments, the polymerblends can be desirably incorporated mobile electronic device components.
