ABSTRACT Butadiene rubber (BR) is one of the most useful and second produced worldwide. Polymerization 1,3-butadiene (BD) a highly stereospecific reaction that offers wide variety BR with different microstructures influences fundamental properties rubber. Since first successful polymerization conjugated diene using Ziegler–Natta–based catalyst (TiCl4 or TiCl3 aluminum alkyls) in 1954, research ...

This article represents data on the effect of organometallic iron complexes: ferrocene, dicarbonyl dimer cyclopentadienyl and tricarbonyl cyclooctatetraene copolymerization methyl methacrylate (MMA) acrylonitrile (AN) initiated by benzoyl peroxide. It is shown that introduction metal complexes their structure affect initial rate copolymerization, form diagrams composition obtained copolymers, v...

Syndiotactic polystyrene (SPS) refers to a type of thermoplastic material with phenyl substituents that are alternately chirally attached on both sides an aliphatic macromolecular main chain. Owing its excellent physical and mechanical properties, as well chemical stability, high transparency, electrical insulation characteristics, SPS is used in wide variety technical fields. commonly produced...
