Procedimiento

A solution was prepared containing 98.86 wt. % 4-chlorophenyl acrylate and 1.14 wt. % dibutyltin dilaurate. 0.017 g of this solution was added to a vial containing 0.2519 g diisocyanate-terminated polypropylene glycol (MW=2471), 0.047 g α,ω-dihydroxypolypropylene glycol (MW=425), 0.051 g 4-chlorophenyl acrylate, and 0.00063 g Ciba CGI-784 (photoinitiator). The mixture was thoroughly mixed and allowed to cure overnight at room temperature, while protected from light. The polymerization was a step polymerization of the isocyanate groups with the hydroxyl groups to form a polyurethane with dissolved chlorophenyl acrylate monomer. The mixture appeared clear and transparent to the naked eye. Upon exposure to an intense tungsten light, which initiated polymerization of the acrylate monomer, the sample remained clear and transparent, indicating the compatibility of the monomer and the matrix polymer.
