Abstract
A thermosensitive copolymer may include a first repeating unit having a temperature-sensitive oligomer and a second repeating unit having an ionic moiety and a counter ion to the ionic moiety. The temperature-sensitive oligomer may be an oligomer including a repeating unit derived from a unsaturated monomer with a moiety represented by Chemical Formula 1 or Chemical Formula 2, or an oligomer including a repeating unit derived from a heterocyclic compound having C, N, O, and a C═N bond in its ring.*—C(═O)N(R)(R)  [Chemical Formula 1]Rand Rmay each independently be hydrogen or a linear or branched C1 to C6 alkyl group, a C3 to C7 cycloalkyl group, or a C6 to C10 aryl group, Rand Rmay not both be hydrogen, and Rand Rmay be combined to form a nitrogen containing heterocycle. Rmay be a C2 to C5 alkylene group.
