摘要:

AbstractThe structure formation via spinodal decomposition is monitored by transmission electron microscopy (TEM) and small angle light scattering (SALS) using hexahydrophthalic anhydride cured bisphenol A diglycidyl ether mixed with bis(4‐hydroxybenzoate)‐terminated poly(tetrahydrofuran) segmented poly(hydroxyether). The poly(tetrahydrofuran) (PTHF) segment has a number average molecular weight of 4500 g/mol. There is good agreement between the particle—particle spacing obtained from the maximum of SALS traces and the digital image analysis of TEM micrographs. Time‐resolved SALS measurements are used to study the phase separation kinetics in the epoxy/diol‐terminated PT

摘要:

AbstractA new apparatus which makes it possible to measure flow small‐angle light scattering (“flow‐SALS”) and to observe the development of the supramolecular structure by an optical microscope (“shear microscopy”) has been developed in our laboratory. It simultaneously provides information on reciprocal space from SALS and on real space from optical microscopy. Therefore, the development of the supramolecular structure in systems such as polymer solutions and polymer mixtures as well as liquid crystals and colloidal systems under shear can be investigated in depth. Shear‐induced phase separation and shear‐induced homogenization of some polymer solution systems were investigated using
