Abstract
A thermoplastic elastomer composition includes: a thermoplastic elastomer having a carbonyl-containing group and a nitrogen-containing heterocycle in a side chain thereof; and an amino group-containing compound. The thermoplastic elastomer composition retains excellent recycle property, and also has excellent mechanical characteristics and compression set (shape retention). Thus, it is of extremely superior industrial applicability and environmental protection effect.
