実験手順

An acrylate urethane oligomer composition was prepared in the following manner. A flask was charged with 202.8 g of PPG 1025 (polypropylene glycol with average molecular weight of 1025), 83.2 g of PPG 425 (polypropylene glycol with average molecular weight of 425), 221.6 g of isobornyl acrylate, 150.0 g of diphenylmethane 4,41 diisocyanate and 0.4 g of dibutyltin dilaurate. The mixture was heated at 80° C. for two hours. Hydroxyethyl acrylate, 23.2 g, was added and the heating continued for one hour. Ethanol, 9.7 g, was added and heating continued until the isocyanate band in the IR at 2268 cm-1 disappeared. The still warm product was diluted with 211.6 g of tetrahydrofurfuryl acrylate, 35.2 g acrylic acid and 35.2 g of Darocure 1173 initiator which is 2-hydroxy-2-methyl-1-phenyl-propane-1-one, a product of Ciba-Geigy. After thoroughly mixing, the mixture was poured warm into an opaque container. The yield of colorless product was 973 g with a viscosity of 8100 cP.
