REACTIVE MESOGEN BASED POLYMER PARTICLES

摘要

This invention relates to a process for the preparation of monodisperse optical and shape anisotropic polymer particles comprising monomer units of at least one reactive mesogen, such particles per se, the use of these particles for the preparation of optical, electrooptical, electronic electrochemical, electrophotographic, electrowetting and electrophoretic displays and/or devices and security, cosmetic, decorative, and diagnostic applications, and electrophoretic fluids and displays.

主权项

1. A process for the preparation of polymer particles with optical anisotropy and shape anisotropy by dispersion polymerisation comprising
a) forming a solution comprising at least one reactive mesogen having a molecular structure providing non-covalent interactions in the polymer particles, at least one solvent, at least one initiator, optionally at least one surfactant, and optionally at least one co-monomer b) polymerising the solution, and optionally c) separating, washing and/or drying the polymer particles.
