Abstract

The joint adhesion strength of low density poly ethylene to thermoplastic plasticized starch (TPS) and their compatibilized versions with poly (ethylene-co-vinyl acetate) (EVA), maleated polyethylene (PE-g-MAH) and maleated styrene-ethylene-butadiene-styrene block copolymer (SEBS-g-MAH) were investigated with peel-test. For localization of the compatibilizers at PE/TPS interface, they were blended with TPS. In addition, thermodynamic work of adhesion between joint components was evaluated by contact angle measurements by applying the existing theories.The results obtained showed the thermodynamic work of adhesion increment from 64 mJ/m2 for PE/TPS to 70, 79, 86 mJ/m2 for compatibilized interface by EVA, PE-g-MAH, and SEBS-g-MAH, respectively. The adhesion improvement was attributed to comatibilizer migration to the interface during high temperature joint formation and resultant enhanced stress transfer capability at the interface. Furthermore, joint loss function was to depend not only on joints main components tan d ratio at room temperature but also on tan d of the thin layer of compatibilizers. Therefore, a new parameter was introduced namely tan d of the peel arms to the adhesive tan 8 multiplied by the compatibilizers tan d to rationalize the observed data.
