Beschreibung
Zusammenfassung:	The present invention provides an ultraviolet-curable acrylic polymer that exhibits excellent adhesive properties irrespective of the surface roughness of an adherend, that exhibits excellent thermal stability, excellent coatability, and excellent adhesive properties, and that is usable as an ultraviolet-curable hot-melt adhesive. The ultraviolet-curable acrylic polymer of the present invention comprises: a (meth)acrylate unit not intramolecularly having an ultraviolet reactive group or a carboxy group; and a monomer unit intramolecularly having an ultraviolet reactive group in a prescribed amount, respectively, wherein the polymer contains a prescribed amount of a (meth)acrylate unit serving as a main unit of the (meth)acrylate unit not intramolecularly having an ultraviolet reactive group or a carboxy group, has, at an end, a residue of a thiol compound, has a predetermined range of a molecular-weight distribution, and exhibits a predetermined range of a post-curing gel fraction, exhibits a predetermined range of a change ratio in terms of weight-average molecular weight after heating, and exhibits a predetermined range of a post-ultraviolet-curing tensile-shear strain tanθ.
