Claim:
1. A method for producing a multiple glazing unit with variable diffusion by liquid crystals comprising: applying, on a first electrode arranged on an internal face of a first substrate, a material called pre-seal containing at least one precursor of a crosslinked polymer so as to form a strip, delimiting a space, the pre-seal being applied to form an adhesive seal upon cross-linking; depositing, on the first electrode, a liquid crystal composition containing liquid crystals in a polymer matrix, the polymer matrix comprising the at least one precursor of the crosslinked polymer; assembling the first substrate with a second substrate so the internal face of the first substrate faces opposite an internal face of the second substrate, wherein assembling comprises at least one of calendaring and pressing, such that the pre-seal in the form of the strip is in contact with the liquid crystal composition, thereby providing an assembly; and after assembling, at least one of irradiating the assembly with ultraviolet radiation (UV) and heating the assembly so as to crosslink the pre-seal and polymerize the liquid crystal composition, wherein the pre-seal is based on acrylate and free from precursor of epoxy polymer and the liquid crystal composition is based on acrylate and free from precursor of epoxy polymer.
