A silane functionalized block copolymer (SiHSBC) is disclosed comprising: 80 to 99.90 wt. % of a hydrogenated styrenic block copolymer (HSBC) and 0.1 to 20 wt. % of a silane, based on the total weight of the SiHSBC. The HSBC is obtained by hydrogenation of a styrenic block copolymer (SBC) comprising at least one polymer block A derived from a vinyl aromatic monomer, and at least one polymer block B derived from a conjugated diene monomer. The polymer block B has greater than 80 wt. % of a polymerized 1,3-butadiene monomer, based on the total weight of the polymerized conjugated diene monomer in the polymer block B. The SiHSBC as well as thermoplastic elastomer composition containing the SiHSBC show improved adhesion to polar and non-polar substrates without the need of an adhesive layer or primer layer.
