Crystalline alternating ethylene‐butadiene copolymers

Abstract

The copolymerization of ethylene with butadiene at −25°C. in the presence of co‐ordinated anionic catalytic systems, prepared at −78°C. from a vanadium compound, organometallic compounds of aluminum and a weak LEWIS base, yields copolymers with particular crystalline structure. By fractionation of crude products, crystalline ethylene‐butadiene copolymers were obtained, the crystalline structure of which was attributed to a succession of ethylene units regularly alternating with trans‐buta‐1,4‐dienic units.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
