Versuchsvorschrift

A quantity of 0.1 moles of isocyanate terminated prepolymer and 0.1 ml of dibutyltin laurate were charged to a 500 ml glass kettle. The mixture was heated at 70° C. and air was purged through the reaction mixture and a solution of diol (0.05 moles) was added dropwise while the mixture was stirred at 200 RPM. After a two hour reaction, hydroyethyl acrylate (0.1 moles) was added to cap the residual isocyanate and the temperature of the kettle was increased to 77° C. After another two hours, a sample was withdrawn for analysis. The remainder was transferred to a bottle and stored in darkness.
