Abstract

A modified maleated polyethylene (MAPE) was blended in a twin screw extruder with the percentage of maleation of 9%. The presence of the maleic anhydride group on the polyethylene backbone increased the ability to bonding with any surface or compound that has functional groups. The use of the maleated polyethylene as a compatibilizer in the polyblend showed high effect in the compatibility between the polymer and the sample in term of the rheological properties. This paper presents the results of an experimental study of the oscillating flow (shark skin and spurt defect) of medium density polyethylene (MDPE) with 1% maleated polyethylene (MAPE). It showed the disappearance of the sharkskin from polyethylene surface and a complete elimination of discontinuity in the flow curve of MDPE, thus disappearance of the spurt defect phenomena.
