Abstract
A block copolymer, a method for preparing a block copolymer, a resin composition, and a film are provided. The block copolymer can be useful in inhibiting complete separation of the hard segment even under a severe high-temperature condition by increasing the chemical cross-linking density around the hard segment without causing an increase in glass transition temperature of the hard segment, thereby maintaining high-temperature durability.
