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.
