Abstract
This document relates to adhesive compositions comprising 1) a thermoplastic vulcanizate of thermoplastic polyurethane and at least partially crosslinked rubber, and 2) an adhesion modifying amount of styrenic block copolymer. These compositions are especially useful in adhering to polar engineering thermoplastics and so find utility in laminates and composite articles comprising at least one polar engineering substrate and the described adhesive compositions.
