PHOTOCHROMATIC POLYMERIZATION-APPROVAL COMPOSITION, PHOTOCHROMIC NETWORK OPTICAL MATERIAL AND METHOD OF ITS PRODUCTION Russian patent published in 2017 - IPC C08L33/08 C08L33/10 C08L33/12 C08K3/40 C08F2/48 G02B5/23

Abstract RU 2626640 C9

FIELD: physics.

SUBSTANCE: proposed composition consists of a silicate glass powder doped with copper chloride CuCl nanocrystals, a mixture of radically polymerizable compounds and a polymerization initiator. One component of the polymerizable compounds is a liquid oligomer with two (meth) acrylic groups bound by a divalent radical containing aromatic groups having at least one acid group -COOH, the refractive index of which is lower than the refractive index of said doped silicate glass.

EFFECT: composition provides a photochromic mesh optical material in the absence of a solvent in a simplified technology in the form of a free film, which greatly expands the scope of this material.
