Abstract
The application of the miniemulsion process to synthesize polyurethane disp ersions with diameters of about 200 nm in a one-step procedure, free of mol ecular weight restrictions, is described. With IR and NMR spectroscopy, it is shown that the reaction of the diisocyanate with the diol is the main re action, whereas the reaction with water is only a side reaction. Differenti al scanning calorimetry measurements and transmission electron microscopy a re used to characterize both polymer and latex properties. (C) 2001 John Wi ley & Sons, Inc.
