실험 절차

968 g of the reaction product of bisphenol A-bis-glycidyl ether and acrylic acid (containing 3.7 gram equivalents of OH) described in Example 1 were dissolved in 850 g of methylene chloride, followed by the addition of 0.6 ml of a concentrated zinc octoate solution and another 0.5 g of p-methoxy phenol. 168 g of hexamethylene diisocyanate (2 gram equivalents of NCO) were then added dropwise while the solution was boiled under reflux. After 24 hours' refluxing, an NCO-content of 0.5% was determined and 128 g of succinic acid anhydride (1.28 gram equivalents of anhydride) were added to the boiling solution. After another 12 hours, a clear solution was obtained to which 25.8 g of tert.-butyl anthraquinone (photoinitiator) were added, and the solution was left to cool.
