Abstract
Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate polymers, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinkable and crosslinked compositions are free or substantially free of tackifiers. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.
