Toxicity of styrene and styrene oxide on chick embryos

Toxicology, 1977
Styrene and styrene oxide were injected into the air space of fertilized chicken eggs at different times during an incubation period of 14 days. The toxicity of styrene and styrene oxide when injected on the fourth day of incubation revealed an LD50 of 40 mumol/egg and 1.5 mumol/egg, respectively.

Styrenic Plastics

2008
This chapter on styrenic plastics covers a broad class of polymeric materials of which an important part is styrene. Chemical structures, manufacturers, and trade names along with typical end uses of the plastics are included. Where available, there are sections covering fatigue data and tribology data in graphical and tabular forms.

Scandium Half-Metallocene-Catalyzed Syndiospecific Styrene Polymerization and Styrene−Ethylene Copolymerization:  Unprecedented Incorporation of Syndiotactic Styrene−Styrene Sequences in Styrene−Ethylene Copolymers

Journal of the American Chemical Society, 2004
On treatment with 1 equiv of [Ph3C][B(C6F5)4], the scandium half-sandwich bis(alkyl) complex (C5Me4SiMe3)Sc(CH2SiMe3)2(THF) showed extremely high activity (up to 1.36 x 104 kg of sPS/(mol Sc.h)) and syndiospecificity (rrrr > 99%) for the polymerization of styrene at room temperature in toluene.

Effect of styrene–isoprene–styrene, styrene–butadiene–styrene, and styrene–butadiene–rubber on the mechanical, thermal, rheological, and morphological properties of polypropylene/polystyrene blends

Journal of Applied Polymer Science, 2003
AbstractThe mechanical, thermal, rheological, and morphological properties of polypropylene (PP)/polystyrene (PS) blends compatibilized with styrene–isoprene–styrene (SIS), styrene–butadiene–styrene (SBS), and styrene–butadiene–rubber (SBR) were studied.

Compatibility effect of radiation‐grafting‐functionalized styrene–butadiene–styrene on polyamide 6/styrene–butadiene–styrene blends

Journal of Applied Polymer Science, 2008
AbstractStyrene–butadiene–styrene (SBS) was grafted with dibutyl maleate (DBM), methacrylic acid (MAA), or maleic anhydride (MAH) by 60Co γ‐rays. The grafted SBS was blended with polyamide 6 (PA6). The compatibility of the PA6/SBS blends was studied with scanning electron microscopy and rheological measurements.

Evidence for DNA and Protein Binding by Styrene and Styrene Oxide

Critical Reviews in Toxicology, 1994
Styrene is metabolized to styrene oxide, a direct-acting mutagen and carcinogen. Styrene oxide reacts with DNA mainly at the N-7 position in guanine, but also at other sites and with other bases. Substitution occurs at both the alpha- and beta-positions of the styrene molecule.

Styrenics: polystyrene and styrene copolymers

1998
The first modification of rubber by incorporation of polystyrene (PS) is credited to Francis Edward Matthews, who during the years 1911-1913 (Figure10.1) received several international patents for the manufacture of lacquers and ‘articles that are normally made of hard rubber, celluloid, vulcanite, ebonite, glass, wood and similar materials’.

Comparisons of styrene ionomers prepared by sulfonating polystyrene and copolymerizing styrene with styrene sulfonate

Journal of Polymer Science: Polymer Chemistry Edition, 1985
AbstractAs part of a continuing study of ion‐containing polymers, a comparison has been made on styrene‐based sulfonate ionomers obtained by two different processes. Copolymers of styrene with sodium styrene sulfonate (SSS) have been compared with corresponding polymers obtained by the sulfonation/neutralization of preformed polystyrene (S–PS).
