Abstract: Described herein is an adhesive composite composition. The composition comprises: a plurality of polymeric microspheres dispersed within a (meth)acrylate-based matrix, wherein the polymeric microspheres are derived from 20 to 99 wt % of a (meth)acrylate monomer having a Tg above room temperature and at least 1 wt % of a polar (meth)acrylate monomer; and the (meth)acrylate-based matrix is derived from a C1 to C20 (meth)acrylate ester monomer and at least 1 wt % of a (meth)acrylate macromer. In some embodiments, these composite adhesives show good impact resistance and good shear. In one embodiment, an ionic liquid is added to the adhesive composite composition to aid in electro-debonding of articles.

Abstract: Described herein is a release coating comprising a blend of: (a) a first polymer, wherein the first polymer is a silicone-containing (meth)acrylic polymer; and (b) a second polymer, wherein the second polymer comprises the polymerization reaction product of: (i) a first monomer having an alkyl group with 12 to 24 carbon atoms, a linking group containing a nitrogen or ester group, and a free-radically polymerizable (meth)acryl group; and (ii) a second free-radically polymerizable monomer having less than 12 carbon atoms. Such release coatings can be coated onto a substrate and used as a release coating for pressure sensitive adhesives.

Abstract: A release composition comprising a waterborne latex polymer particles comprising the polymerization reaction product of: i) a first monomer having an alkyl group with 12 to 24 carbon atoms, a nitrogen-containing or ester linking group, and a free-radically polymerizable (meth)acryl group; ii) a second free-radically polymerizable monomer having less than 12 carbon atoms; and iii) a free-radically polymerizable surfactant; and an aqueous carrier liquid. Also described is a method of making a release coated article and articles.
