Stereoselective Cyclopropanation by Cyclocopolymerization of Butadiene

Journal of the American Chemical Society, 2002
An unprecedented cyclopropanation by cyclopolymerization reaction is presented. In particular, catalytic copolymerization processes of ethene and butadiene lead with high trans selectivity to a complete cyclocopolymerization of butadiene units. Ethene-based copolymers including cyclopropane and cyclopentane rings, which can be relevant to polyolefin ...

Mutagenicity of butadiene and butadiene monoxide

Biochemical and Biophysical Research Communications, 1978
Abstract Incubation of S. typhimurium strains TA1530 and TA1535 in the presence of gaseous butadiene increased the number of his+ revertants/plate. This mutagenic effect occured in absence of fortified S-9 rat liver fraction. In its presence, the mutagenic effect seemed to be dependent on its composition. With butadiene monoxide, a reversion to

The reactivity of 1,3-butadiene with butadiene-derived popcorn polymer

Journal of Hazardous Materials, 2004
Adiabatic calorimetry performed on butadiene-derived popcorn polymer samples from industrial facilities has revealed exothermic behavior accompanied by non-condensible gas production, indicative of possible decomposition, at elevated temperatures. In the presence of low concentrations of 1,3-butadiene, reactivity is observed at temperatures of 60-70 ...

Macromolecular adducts of butadiene

Toxicology, 1996
Butadiene (BD) is an important industrial chemical classified as a probable human carcinogen. Marked species differences in susceptibility to the carcinogenic effects of BD have been observed, possibly due to the differences in its metabolism. In this work, guanine and adenine adducts formed by the reactive metabolites of BD in vitro were isolated and ...

The microstructure of butadiene unit in the copolymer of butadiene with styrene

European Polymer Journal, 1983
Abstract Copolymerization of butadiene with styrene and diad analysis of the copolymers by 13 C-NMR were attempted to obtain information on the penultimate unit effect on the microstructure of the butadiene unit. As catalyst, Ni(acac) 2 , Ni(benzoate) 2 and Co(acac) 3 were used together with Et 1.5 AlCl 1.5 .
