Abstract
Thermoplastic vulcanizate compositions having good adhesion to unheated polar substrates include an amount of functionalized polyolefin that comprises greater than 80% of the total polyolefin of the TPV. The functional group may be an anhydride. Exemplary TPVs may further include polyamide, and an elastomer, which may include one or more of conjugated diene rubber, unsaturated styrenic triblock copolymer rubber, hydrogenated styrenic triblock copolymer rubber, ethylene/alpha-olefin rubber, and ethylene/alpha-olefin/non-conjugated diene rubber. The TPVs may have hardness values of less than 85 Shore A and peel forces with respect to unheated polar substrates of greater than 15 pli. Articles comprising polar substrates and TPVs are also taught.
