Abstract

Polymer particles made from copolymers of multifunctional (meth)acrylate monomer and multifunctional aromatic monomers are disclosed. Also disclosed are methods of improving the compression characteristics of (meth)acrylate polymer particles by copolymerizing with a multifunctional (meth)acrylate monomer a multifunctional aromatic monomer. The particles are of a size, uniformity, and contain physical characteristics that make them ideally suitable for use as spacers in liquid crystal display devices.
