The 1990 Clean Air Act Amendments list several volatile organic chemicals as hazardous air pollutants, including ethylene oxide, butadiene, styrene, and acrylonitrile. The toxicology of many of these compounds shares several common elements such as carcinogenicity in laboratory animals, genotoxicity of the epoxide intermediates, involvement of cytochrome P450 for metabolic activation (except et...

Acrylonitrile–butadiene–styrene (ABS) is one of the most extensively used engineering polymers. It necessary to study recycling ABS because environmental, economic and energy reasons. In this study, an resin was processed using a torque rheometer at different temperatures for numbers cycles. Pyrolysis gas chromatography mass spectrometry (Py-GC/MS) effects processing parameters on additives. Fo...

Data are presented on the acute toxicity (mortality only) of the thermal degradation products of polymers obtained by two methods of degradation. One system utilized a slowly increasing temperature (5 degrees C/min) and gradual degradation of the polymer with the rats being exposed to degradation products as they were evolved. In this system the more toxic polymers included wool, polypropylene,...

Material extrusion is one of the most widespread additive manufacturing processes because its low-cost implementation and flexibility in design. In this study, integrated digital image correlation used for identification constitutive parameters two configurations acrylonitrile butadiene styrene (ABS) samples. It shown that an isotropic elastoplastic model calibrated from single edge notched ten...

Acrylonitrile–Butadiene–Styrene (ABS) polymers have a complex microstructure which is formed during the grafting reaction of polybutadiene seed latex. During reaction, some styrene-acrylonitrile (SAN) chains are grafted onto (PB) backbone chains, and this critical to achieve effective dispersion compatibility both phases. Therefore, accurate characterization properties helps understanding polym...
