This abstract first appeared for US patent application 18723907 titled 'COMPOSITE ADHESIVES

Original Abstract Submitted

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.
