Abstract: An adhesive composition includes a first acrylic polymer preparable from first components and a second acrylic polymer. The first components comprising i) a branched first alkyl (meth)acrylate having from 4 to 22 carbon atoms, and ii) at least one of acrylic acid and methacrylic acid. The second acrylic polymer is preparable from second components comprising iii) at least one second alkyl (meth)acrylate having from 4 to 22 carbon atoms, iv) a (meth)acrylamide represented by the formula wherein R1 is H or methyl, and R2 and R3 each independently represents H or an alkyl group having from 1 to 8 carbon atoms, or taken together R2 and R3 may form a divalent alkylene group having from 4 to 6 carbon atoms, and v) at least one high Tg macromer having a terminal free-radically polymerizable unsaturated group, the high Tg macromer having a Tg of at least 45° C. Based on the combined total weight of the at least one first acrylic polymer and the at least one second acrylic polymer, the at least one second acrylic polymer is present at a level of from 5 to 40 percent by weight. Methods of making the adhesive composition are also disclosed.

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 copolymers plus a tackifier, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

Abstract: Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.
