Abstract: Disclosed herein are compositions comprising a first copolymer derived from monomers comprising a (meth)acrylate monomer, an acid monomer, and optionally at least one additional monomer selected from the group consisting of styrene, α-methyl-styrene, vinyl toluene, and mixtures thereof, wherein the first copolymer is derived in the absence of a molecular weight regulator and wherein the first copolymer has a weight average molecular weight of less than 10,000 Daltons, and methods of making the same. The compositions and methods disclosed can be used, for instance, in pressure-sensitive adhesive applications.

Abstract: Styrenic (meth)acrylic oligomers that are prepared at lower temperature than conventional solid grade oligomers, or are hydrogenated, contain fewer terminal vinylic unsaturations, when compared to such conventional styrenic (meth)acrylic oligomers prepared by the customary high temperature processes. Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers.
