Beschreibung
Zusammenfassung:	The present invention provides a block copolymer (A) having a first segment and a second segment, wherein the first segment is a polymer segment formed by a monomer component comprising a specific hydroxyl group-containing monomer and a specific polycyclic aliphatic hydrocarbon group-containing monomer, the second segment is a polymer segment formed by a monomer component comprising a specific long-chain alkyl group-containing monomer, and the content ratios of the monomers are specified amounts in all of the monomer components that form the block copolymer (A). The block copolymer enables the preparation of a release agent composition having a satisfactory usable time even when a crosslinking agent is used, and therefore enables the production of a release sheet having excellent releasability and hardness. 本发明提供一种嵌段共聚物，其为具有第一链段与第二链段的嵌段共聚物(A)，所述第一链段为由包含特定的含羟基单体及特定的含多环式脂肪族烃基单体的单体成分形成的聚合物链段，所述第二链段为由包含特定的含长链烷基单体的单体成分形成的聚合物链段，在形成所述嵌段共聚物(A)的所有单体成分中，上述各单体的比例为特定量。该嵌段共聚物即使在使用了交联剂的情况下，也能够制备具有良好的适用期的剥离剂组合物，且能够制造具有优异的剥离
