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...

In a follow-up study of mortality among North American synthetic rubber industry workers, cumulative exposure to 1,3-butadiene was positively associated with leukemia. Problems with historical exposure estimation, however, may have distorted the association. To evaluate the impact of potential inaccuracies in exposure estimation, we conducted uncertainty analyses of the relation between cumulat...

The enormous increase in the commercial demand for the rubber and the probability of the continuance of this increase in view of the great variety of purposes to which the material can be applied, demands a thorough understanding of its structure, composition and physical/mechanical properties. Hydrogenated Nitrile Butadiene rubber (HNBR) and Chlorosulphonated monomer (CSM) were investigated in...

The study deals with the Payne effect (a substantial decrease in the storage modulus of a particle-reinforced elastomer with an increase in the amplitude of mechanical oscillations). The influence of temperature, concentration of filler and amplitude and frequency of strains is analyzed on the mechanical response of filled rubbery polymers. Constitutive equations are derived using the concept o...

Fused filament fabrication (FFF) is a common additive manufacturing method for polymers that has been widely adopted due to its low cost and ease of use. However, FFF remains limited in high performance applications the weak mechanical properties welds between printed fibers, including parts manufactured from acrylonitrile butadiene styrene (ABS). This study uses atomic force microscopy (AFM) o...

Epidemiologic studies can measure exposure to volatile organic compounds (VOCs) using environmental samples, biomarkers, questionnaires, or observations. These different exposure assessment approaches each have advantages and disadvantages; thus, evaluating relationships is an important consideration. In the National Children's Vanguard Study from 2009 to 2010, participants completed questionna...
