Glycidyl methacrylate (GMA) grafted acrylonitrile-butadiene-styrene (ABS) in the presence of styrene (St) monomer (AGS) was used as a compatibilizer in the immiscible poly(butylene terephthalate)/poly(acrylonitrile-styrene-acrylate) (PBT/ASA) blends. SEM analyses display a better dispersion of ASA particles in the PBT matrix with the content of AGS less than 4.0 wt% compared with the PBT/ASA blends. Rheological measurements show that the melt elasticity and melt strength of blends increase with increasing ABS-g-(GMA-co-St) content. The behavior of blends shifts from “liquid-like” to “solid-like” and the relaxation time moves to higher values by introducing AGS. 3.0 wt% AGS is the optimum concentration for PBT/ASA system.

AbstractThe front covers of Motorola cellular phone housings, which were composed of 62.2 wt% of polycarbonate (PC) /acrylonitrile-butadiene-styrene (ABS), were ground and separated from the undesired materials using sink-float methods. The sink-float methods in water and salt were used to remove the floating materials such as the adhesive strips and the foams, and to separate the metal parts where the recovery ratios were 92.8 and 40.5 %, respectively. The separation of residual wires and button rubbers, which could not be done by the sink-float process in water, was preformed using V-Stat Triboelectric Separator (Outokumpu Technology) of a roll separator that also provided the effective methods to separate the ground metals that had existed in the printed circuit boards where the recovery weight ratio of metal parts was 19 wt%. The separated PC/ABS’s could be compounded with the ground circuit boards or the thermoplastic elastomer called Engage®, or the reactive species of glycidyl methacrylate (GMA).
