Conditions

Temperature
125 °C

Procedure

An acid-terminated caprolactone acrylate was prepared by combining 37.0 g of phthalic anhydride, 19.25 g of hexahydrophthalic anhydride, and 129.0 g of TONE Monomer M-100 in a glass, four-neck reaction flask equipped with a stirrer, a thermometer, an air inlet and an air outlet, and heating them at 125° C. for 3.5 hours. The product was recovered and found to have an Acid Number of 114 and a viscosity of 1690 cp when measured at 25° C.
