  Abstract

In the present research, high-density polyethylene (HDPE) and polyester, poly(ethylene terephthalate) (PET), residue from platforms offshore, were blended in the presence of a coupling agent, a polyethylene-grafted maleic anhydride (HDPE-g-MA). The HDPE/HDPE-g-MA/PET blends were processed by melt mixing in a twin-screw extruder, using a factorial design. The processing conditions were set so that the PET remained in the fiber shape in the melt. The effect of a nanoclay, montmorillonite clay (MMT), in the blends as co-compatibilizer was evaluated by mechanical, rheological, thermal and morphological analyses. The results showed that there is an interaction between PET fibers and MMT nanoclay. The yield properties (stress and strain) decreased with the addition of PET fibers. Young셲 modulus and stress at break property increased with high PET fibers and MMT contents. An interaction between PET and MMT contents was also observed on the maximum degradation temperature (TM횁X): the compositions with higher PET and MMT contents showed a higher thermal stability. The rheological results showed that a more pronounce solid-like behavior was achieved when MMT was added in the HDPE/ HDPE-g-MA/PET blend. These results indicate that MMT nanoclay has potential as co-compatibilizer in HDPE/HDPE-g- MA/PET blends. This was due to its preferential localization in the PET fiber domains and interphase between HDPE and PET, as showed in SEM analysis.
