This invention relates to a technology for manufacturing multilayer optically transparent products. The aim of the invention is to increase the stability of the glued product while expanding the temperature range of thermal shock. The invention allows, as an adhesive layer of a multi-layer optically transparent product, to increase the stability of the glued product while expanding the temperature range of thermal shock to 378 ° C due to a new copolymer based on pn-alkylstyrene (C 5 - C 10 ), p-alkyl-crylate ( C 4 - C 12 ) and a crosslinking monomer from the group comprising bie-methyl-1, 1, 3, 3-tetramethyldisiloxane dimethacrylic ester or diethylene glycol dimethacrylic ether, in a weight ratio of 71.3-81.2% by weight, 3 - 26.9 wt. %, 0.3 - 1.8 wt.%. 1 tab. |
