Versuchsvorschrift

An amount of dicyclohexylmethane-4,4′-diisocyanate (H12MDI) was added to a reaction vessel at room temperature. Heating jacket temperature was adjusted to 45° C. suspended in a room temperature water bath and stirred. When the reaction batch temperature was 45° C., dibutyltindilaurate, as catalyst, and hydroquinone methyl ether, as free-radical polymerization inhibitor, were also added. Pentaerytritol triacrylate was added incrementally to control exothermic activity. When the exothermic activity ceased the result of Stage 1 was added and batch temperature was adjusted to 60° C. The batch was kept at 60° C. until no free isocyanate was detected by FTIR. Viscosity of the result was 11,750 cP at 25° C. and it readily mixes with water. When the result was diluted with equal amount (by weight) of water viscosity was 150 cP at 25° C.
