実験手順

672.0 g of a polyester of adipic acid and neopentyl glycol with an OH number of about 200, 140.0 g of hydroxyethyl acrylate, 0.6 g of hydroquinone monomethyl ether, 1.21 g of 2,6-di-tert-butyl-4-methylphenol, 0.12 g of cesium acetate were initially introduced into a round-bottomed flask and heated to 50° C. 400.0 g of isophorone diisocyanate were then added dropwise over the course of 30 minutes. The mixture was left to react for a further 7 hours at 90-95° C., during which the NCO content dropped to 0.56%. The mixture was cooled to 60° C., then 520.0 g of ethanol were added and the mixture was left to react further for about 2 hours at 65-70° C. until the isocyanate content (NCO value) had dropped to 0. The resulting resin was filtered over a 50 μm filter and bottled.
