Abstract

The reaction of styrene-maleic anhydride (SMA) with polyethylene/methyl acrylate/glycidyl methacrylate (E-MA-GMA) was studied in a batch mixer and in a corotating twin screw extruder. Also, the mixing of a nonreactive blend of SMA with polyethylene/methyl acrylate (E-MA), with similar rheological properties to E-MAG-MA, was studied under the same processing conditions. The mixing products of reactive and nonreactive systems exhibited drastically different properties. Reactive blends showed higher tensile modulus, tensile strength, strain at break and complex viscosity in comparison to non-reactive blends. The reactive blends had also finer morphology than the non-reactive ones.
