Effect of the Compatibilizer on Phase Morphology

The addition of a compatibilizer in a blend obviously changes its phase morphology development mainly by reducing the 

The inverse of breakup time %) can be expressed as a function of the difference between the initial capillary number and that of the compatibilized blend Ca - Caf). Then the coalescence can be described by the derivative of the droplets number with respect to time  

In steady-state condition, the following equation is valid ( ) +( ) =0 (22.5) 

This complex expression may be solved only when simplifying assumptions are made because of interdependence of the variables. Supposing, for example, a constant density of copolymer on the interface, n, can be considered constant, so that the dependence of D on / j is the same as for blends without compatibilizer using the right value of a and P.
