On the electron structure of some hydrocarbons, fluorocarbons and organometallic compounds

Such materials as polyethylene, polypropylene, polyisobutylene have about the same initial density and the same elemental composition (CH2), only the structures of the initial molecules differ. As the analysis conducted shows, the behaviours of polyethylene and polypropylene under compression are similar and described with one and the same equation of state (with the same parameters). The correlation behaviour of compressibility of hydrocarbon and fluorocarbon compounds of CF2 type is shown. This may be because of identical electron configuration of oxygen-like carbon ion in these compounds.
