The phase separation processes of various thermoplastics modified thermosetting systems including the UCST
LCST systems and the system with complex crosslinking reaction were experimentally studied with emphasis on the temperature dependency of the phase separation time.It was found that the Arrhenius type function can well describe the phase separation time/temperature relation
no matter how the viscoelastic and hydrodynamic factors were changed.Also
the activation energy keeps constant with the variations of TP content
TP molecular weight
curing rate and phase separation detecting means
while it varies with the chemical environment compatibility and the time/temperature dependence of the cure reaction.
