Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive ones. At 25 % PE-F, a maximum in complex viscosity was obtained for the reactive blends. In morphological analysis, the reactive blends showed finer morphology than the non-reactive ones.
