Using two-dimensional time resolved light scattering to study the cure reaction induced phase separation process of epoxy-amine-polyethersulfone blend with secondary phase separation
The generalized two-dimensional correlation analysis based on time-resolved light scattering patterns(2D TRLS) has been employed to study the phase separation process of an epoxy-amine-polyethersulfone blend in which the secondary phase separation takes place.The results of the 2D TRLS provided more detailed information that was not readily observed in the 1D TRLS patterns.(i) During the first process of phase separation,the sequential order of coarsening in size of the domains among the larger and smaller ...
