実験手順: The acrylic monomers generated in Examples 1 and 10-12, 2-OA, 2-EHA, and LA were each prepared into adhesive films using the following procedure. The alkyl acrylate (28.5 g), 0.02 g of IRGACURE 651 (Ciba), 0.3 g of acrylic acid (AA, Alfa Aesar), and 1.2 g of hydroxyethyl acrylate (HEA, Aldrich) were mixed using a magnetic stir bar in a clear glass vial. The glass vial was then purged with nitrogen for 5 minutes to remove dissolved oxygen, and then treated with UV light (365 nm, approximately 5 mW/cm2) until a coatable viscosity was achieved. The target for this step was an approximate viscosity of 3000 cP at room temperature and acrylic conversion of approximately 10%. each prepared into adhesive films The glass vial was then purged with nitrogen for 5 minutes to remove dissolved oxygen treated with UV light (365 nm, approximately 5 mW/cm2) until a coatable viscosity at room temperature
