Fig. 5. Double-logarithmic plots of W/O-encapsulation rates as function of the (a) isocyanate, (b) amine and (c) surfactant concentration. The reaction orders referring to the reactants and S are α = 1, β = 0.3 and γ = –0.1. Experimental conditions are as follows: (a) HDI3:[HMDA] = 10 wt%, TDI:[HMDA] = 2.5 wt%, HDI:[HMDA] = 10 wt%; (b) [TDI] = 2.5 wt%; (c) [HMDA] = 2.5 wt%, [TDI] = 2.5 wt%.
