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 کاملHigh MOF loading in mixed-matrix membranes utilizing styrene/butadiene copolymers.
A series of styrene/butadiene polymers were combined with up to 90 wt% UiO-66 to form mixed-matrix membranes with varying physical properties. Notably, polystyrene-block-polybutadiene (SBS) membranes retained much of the processability and flexibility of the native polymer component and the porosity, chemical tunability, and adsorption of the native MOF.
متن کاملRapid Modular Synthesis and Processing of Thiol−Ene Functionalized Styrene−Butadiene Block Copolymers
Diblock and triblock copolymers of poly(styrene)-block-poly(1,2-butadiene) (PS/PB) and PS/PB/PS were modified by photochemical thiol−ene chemistry to process selected functional nanopatterned polymers, with reaction completion in 1 h. PB molecular weight (MW) and thiol−ene ratios were systematically varied based on a model monomer, boc-cysteamine, to determine the efficiency of the reaction. Th...
متن کاملDetermination of the chemical composition distribution of copolymers of styrene and butadiene by gradient polymer elution chromatography
In order to determine the chemical composition distribution (CCD) of styrene-butadiene copolymers, gradient polymer elution chromatography has been performed. The separation is mainly based on differences in solubility among the copolymer molecules with different chemical composition. The solubility of a copolymer is dependent on the following parameters: temperature, type of solvent/non-solven...
متن کاملSynthesis of new organolanthanide complexes and their use as novel catalysts for polymerization and copolymerization of olefins
The replacement of one of the two C5Me5 ligands in the samarocene(II) complex (C5Me5)2Sm(thf)2 with a monodentate anionic ligand such as OAr, SAr, NR1R2, or CH(SiMe3)2 gave a unique catalytic system, which can not only polymerize styrene and ethylene, but also copolymerize them into block styrene–ethylene copolymers under the presence of both monomers. On the other hand, the addition of an appr...
