Claim:
1. In situ polymerization process for obtaining an electro-optical apparatus consisting essentially of: (a) introducing at least one monomer having an acrylate or methacrylate into a cell formed by two surfaces of glass separated by 1 to 100 microns by a spacer, wherein a first of the glass surfaces comprises a thin layer of a material acting as an electrode and a second of the glass surfaces comprises a thin layer of a material acting as a counter electrode, (b) maintaining said at least one monomer at a temperature which is above its melting temperature, (c) applying through the electrode and counter electrode a direct current electric field of at least 2.5 V/μm and for a time ranging between 5 minutes and 24 hours to polymerize the at least one monomer to form a polymer, and (d) cooling the polymer to room temperature and removing the applied field.
