Abstract

A super-toughened multiphase thermoplastic composition is provided by combining at least one modified selectively hydrogenated conjugated diene/alkenyl arene block copolymer to which has been grafted an effective amount of succinic groups primarily in the selectively hydrogenated conjugated diene blocks thereof and optionally at least one unmodified selectively hydrogenated conjugated diene/alkenyl arene block copolymer with at least one .alpha.,.omega.-polyamide.
