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.

Polymer particles

Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.
