Elaboration and viscosimetric,viscoelastic and rheological studies of a new hexafunctional polyepoxide polymer : Hexaglycidyl ethylene of methylene dianiline

In this work,we studied the viscosimetric,viscoelastic and rheological behavior of a new hexafunctional epoxy polymer: hexaglycidyl ethylene of methylene dianiline (hgemda) which is synthesized in the laboratory and its natural phosphate-based composite as loading. in the first stage,after the synthesis of the macromolecular matrix (hgemda),we crosslinked and formulated it in order to produce a thermosetting technological composite material in the presence of natural phosphate loadings at different percentages (0%,5%,10% and 15%) by adding methylene dianiline (mda) as hardener. secondly,we studied the viscosimetric properties of this epoxy prepolymer by the use of an ubbelohd vb-1423 capillary viscosimeter and the viscoelastic and rheological properties by the use of a rhm01 type rheometer -rd haake. it was very important to specify the influence of natural phosphate in the rheological behavior of nanocomposites based on macromolecular matrix and natural phosphate. © 2017,university of mohammed 1er oujda morocco
