Abstract
The present invention relates to a high impact resistant polymeric composition comprising a polyester and a thermally stable modified selectively hydrogenated block copolymer wherein at least one acid compound or a derivative thereof is grafted to the block copolymer. Poly(alkylene terephthalates) are preferred thermoplastic polyesters. The block copolymer will comprise at least one polymeric block of a monoalkenyl arene and at least one polymeric block of at least one conjugated diolefin.
