Materials Butyllithium solution in hexane (1.6 M) and molybdenum disulfide (MoS2, 99.0% purity) with an average diameter of about 1 μm were purchased from Aladdin. Nitrile rubber (NBR) with acrylonitrile content 40%, was manufactured by Jilin Chemical Industry Company, Jilin, China. 1butyl-3-methyimidazolium chloride ionic liquid was supplied by Henan Lihua pharmaceutical Co., Ltd. The chemical...
This brief article aims to reveal the flexural performance, including the equivalent flexural strength of PVA (Polyvinyl Alcohol) modified concrete by comparing it primarily with that of SBR (Styrene Butadiene Rubber) concrete. This data article is directly related to Karadelis and Lin [6].
To date, epidemiologic research on 1,3-butadiene has consisted of cohort mortality studies of workers in the styrene-butadiene rubber (SBR) and butadiene monomer industries. These studies have been extremely useful both in defining the focus on human health effects to the lymphopoietic cancers and in providing a perspective on which to evaluate the available animal models for human risk assessm...
In order to develop a polycarbonate (PC)/ acrylonitrile-butadiene-styrene (ABS) product with a high content of recycled PC, a low molecular weight virgin PC was added to recycled PC to minimize batch-to-batch property variations in the compounded product. Six PC/ABS blends were prepared on a twin screw extruder by mixing 50 wt% virgin ABS and 0-25 wt% low molecular weight virgin PC with 25-50 w...
The studies on wollastonite reinforced recycled ABS (Acrylonitrile butadiene styrene) composites were investigated. Powder-based with a particle size of 13 microns was mixed Acrylonitrile styrene in various proportions wt.%. Recycled homogeneously and composite prepared using twin-screw extruder it pelletized. specimens the injection moulding process mechanical properties like tensile strength ...
در پیل سوختی پلیمری برای نگهداری هیدروژن و اکسیژن/هوا در ناحیه مربوط به خود، وجود واشر آب بندی در هر سل ضروری است. پایداری واشرهای آب بندی تاثیر بسیار زیادی بر روی طول عمر عملیاتی و عملکرد الکتروشیمیایی پیل سوختی می گذارد. هدف از این تحقیق یافتن ماده الاستومری مناسب جهت استفاده به عنوان آب بند در پیل سوختی پلیمری است. برای این کار چهار نوع ماده الاستومری که بهترین خواص را برای این کار داشتند،...
Synthetic rubber is commonly used in applications in which interaction with a polar matrix is beneficial, and the introduction of polar groups into the polymer can be used to improve this interaction. Styrenebutadiene rubbers and butadiene rubbers containing polar or reactive functionalities have been reported in the academic and patent literature, and select functionalized polymers are manufac...
The eects of ultra-violet irradiation on the microstructure of an oxygen free polymer viz., acrylonitrile-butadiene-styrene and a polymer containing oxygen viz., polycarbonate have been investigated using positron annihilation lifetime measurement. Lifetime results in both polymers in the early stages of irradiation indicate that chain-scission leading to free radical formation is the predomin...
In this paper, graphene oxide/styrene-butadiene rubber (GO/SBR) composites with complete exfoliation of GO sheets were prepared by aqueous-phase mixing of GO colloid with SBR latex and a small loading of butadiene-styrene-vinyl-pyridine rubber (VPR) latex, followed by their co-coagulation. During co-coagulation, VPR not only plays a key role in the prevention of aggregation of GO sheets but als...
The International Agency for Research on Cancer has given the designations of "sufficient evidence" of carcinogenicity of 1,3-butadiene in experimental animals and "limited evidence" of carcinogenicity in humans. To investigate the carcinogenic effect in humans, we conducted a cohort mortality study among 364 men who were assigned to any of three 1,3-butadiene production units located within se...
