    摘要: A toughened multiphase thermoplastic composition is provided by incorporating at least one functionalized, selectively hydrogenated alkenyl arene/conjugated diene block copolymer to which has been grafted an effective amount of carboxyl functional groups primarily in the alkenyl arene blocks thereof with a thermoplastic polyester. The carboxyl functional groups may be in the form of carboxylic acids, their salts, their esters, and combinations of two or more of these.
