Biodegradation of Styrene-Butadiene-Styrene Coploymer via Sugars Attached to the Polymer Chain
A synthetic method was developed to chemically attach few molecules of simple sugars like glucose, mannose, galactose, maltose and xylose (0.09 0.37 wt%) and with quaternary nitrogen pendants (0.42 0.46 atomic%) along the polybutadiene section of polystyrene-block-polybutadiene-block-polystyrene (SBS) block copolymer. These functionalized SBS copolymers were evaluated for biodegradation using t...
متن کاملButadiene and Styrene Risks
The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...
متن کاملVolatile Substances in Polymer Toys Made from Butadiene and Styrene
The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and styrene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known car...
متن کاملsynthesis of ethylene bis-stearamide for acrylonitrile-butadiene-styrene polymer
ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...
متن کاملMechanical, Electrical and Electro-Mechanical Properties of Thermoplastic Elastomer Styrene-Butadiene-Styrene/Multiwall Carbon Nanotubes Composites
Composites of styrene-butadiene-styrene (SBS) block copolymer with multiwall carbon nanotubes (MWCNT) were processed by solution casting in order to investigate the influence of filler content, the different ratio of styrene/butadiene in the copolymer and the architecture of the SBS matrix on the electrical, mechanical and electro-mechanical properties of the composites. It was found that fille...
