Reaction Steps

In a dried test tube, 4 ml. of chloral and 0.4 ml. of phenyl isocyanate were dissolved in 20 ml. of toluene. The resultant mixture was heated to 60°C. and 0.12 ml. of 1-molar lithium tert-butoxide in toluene was added thereto. The test tube was stoppered and the quiescent mixture was cooled to -20°C. The mixture set up in a few minutes to a transparent gel. After 1 hour, the tube was allowed to come to room temperature and to stand overnight. Toluene was partially removed under reduced pressure and the polymer plug was taken out of the test tube. The polymer gel had collapsed and was clear. Toluene and traces of unreacted monomers remaining in the polymer were allowed to evaporate at room temperature in the air. A conherent plug of chloral/phenyl isocyanate copolymer was obtained having the characteristic IR absorption of 5.70 μ.
