Letter

One possible approach to produce useful materials from recycled poly(ethylene terephthalate) (r-PET) is by blending with rubber [1, 2, 3, 4] or fibers [5, 6]. By blending r-PET simultaneous with rubber and short glass fibers (SGF), it is expected that the resulting SGF/rubber/r-PET ternary blends will possess tailored tensile and impact properties. In the production of multi-component blends, it is known that the blending sequence will has strong impact on the morphology and hence mechanical properties [7]. In this study, SGF/rubber/r-PET ternary blends were produced by two different blending sequences. The morphology and properties of the blends will be reported.

The recycled PET used in this study was supplied in pellet form from a local recycling source. The rubber used is a maleic anhydride grafted styrene-ethylene/butylenes-styrene triblock copolymer (MA-g-SEBS) (Kraton FG1901X, Shell Chemical). The short glass fiber (SGF) used is CRARTEC PLUS 183F (Owens Corning). In the...
