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.

Mutagenicity of styrene and styrene oxide

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1977
Abstract Incubation of S. typhimurium strain TA 1535 with styrene increased the number of his + revertants/plate in presence of a fortified S9 rat-liver fraction. Styrene was also highly cytotoxic for Salmonella cells. Styrene oxide, the presumed first metabolite, had a mutagenic effect towards strains TA 1535 and TA 100 both with and without ...

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.

Ferredoxin reductase catalyzes styrene oxidation to styrene oxide

Experientia, 1982
The flavoprotein ferredoxin reductase catalyzed the oxidation of styrene to styrene oxide in the presence of NADPH. This reaction was inhibited by the addition of catalase and superoxide dismutase. The addition of the nonheme iron protein ferredoxin partially inhibited styrene oxidation.

Carbocationic Polymerization: Styrene and Substituted Styrenes

1989
Although the cationic polymerization of styrene and substituted styrenes (referred to here collectively as ‘styrenes’) belongs to one of the oldest and most studied polymerization systems, it is not yet completely understood. In this chapter we shall try to review selectively and critically the existing literature on the cationic polymerization of ...
