The molecular structure of 2,3-dimethyl-2-butene (DMB) is calculated by means of molecular mechanics, using two different force fields and by ab initio calculations, using a 4-31G/4-21G basis set. Both calculational methods show good mutual correspondence, except for the orientation of the ...
Polybutene-1 (PB-1) exhibits excellent mechanical properties, while an unavoidable polymorphic transition from a metastable form II to the stable form I occurs after solidification from the molten state. This transition goes along with a deformation of the crystal lattice corresponding to a lateral ...
The gas phase molecular structure of 2,3-dimethyl-2-butene has been investigated by the electron, diffraction technique. The following structural parameters ( r a structure) have been obtained: C C = 1.336±0.004 Å; C-C = 1.505±0.002 Å; C-H = 1.092±0.003 Å; ∠C C-C = ...

The high affinity of single-site catalysts towards higher olefins is used for producing ethene-/α-olefin copolymers with a very high comonomer incorporation [3] and very long comonomers [4], [5]. Usually butene, hexene, or octene are used as comonomers but also longer olefins were ...
