Random copolymer blends of styrene, para-fluoro styrene and ortho-fluoro styrene [PDF]

open access: yesPolymer, 1993
This study completes the investigation of the phase behaviour of polymer blends involving styrene (S), ortho-fluoro styrene (oFS) and para-fluoro styrene (pFS). As before, due to the proximity of the glass transition temperatures of most blends investigated, the miscibility or immiscibility is established using the alternative thermal analysis method ...

Blends of styrene-butadiene-styrene triblock copolymer with random styrene-maleic anhydride copolymers [PDF]

open access: yesMacromolecular Chemistry and Physics, 2002
Blends of styrene-butadiene-styrene triblock copolymer (SBS) with random styrene-maleic anhydride copolymers (PS-co-MA), having different MA content, were prepared in a Brabender Plastigraph mixer. The presence of polystyrene (PS) blocks in the SBS copolymer and the high styrene content (93 and 86 wt.-%, respectively) in the two kinds of used PS-co-MA ...

Modeling Styrene−Styrene Interactions

open access: yesThe Journal of Physical Chemistry A, 2005
This study is the first step in the systematic investigation of substituted (carboxyl) polystyrene nanoparticles. Understanding the fundamental interactions between the p-carboxyl styrene monomers, where an ethyl group is used instead of a vinyl group (referenced, for convenience, as "p-carboxyl styrene"), provides the basic information needed to ...

StyA1 and StyA2B from Rhodococcus opacus 1CP: a Multifunctional Styrene Monooxygenase System [PDF]

open access: yes, 2010
Two-component flavoprotein monooxygenases are emerging biocatalysts that generally consist of a monooxygenase and a reductase component. Here we show that Rhodococcus opacus 1CP encodes a multifunctional enantioselective flavoprotein monooxygenase system

Identification of a Novel Self-Sufficient Styrene Monooxygenase from Rhodococcus opacus 1CP. [PDF]

open access: yes, 2009
Sequence analysis of a 9-kb genomic fragment of the actinobacterium Rhodococcus opacus 1CP led to identification of an open reading frame encoding a novel fusion protein, StyA2B, with a putative function in styrene metabolism via styrene oxide and ...

Development of a colorimetric dosimeter for styrene exposure in shipyards [PDF]

open access: yes, 2022
Despite the rapid evolution of industrial technologies in the last decades greatly improved many production processes, several industrial sectors still rely heavily on manual labour.

Identification of volatile organic compounds (VOCs) in plastic products using gas chromatography and mass spectrometry (GC/MS)

open access: yesRevista Ambiente & Água, 2014
Plastic materials are widely used in daily life. They contain a wide range of compounds with low molecular mass, including monomeric and oligomeric residues of polymerization, solvent-related chemicals residues, and various additives.
