    en.wikipedia.org/wiki/Ethylbenzene

    Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.

  4. Pendant group - Wikipedia

    en.wikipedia.org/wiki/Pendant_group

    For example, the phenyl groups are the pendant groups on a polystyrene chain. Large, bulky pendant groups such as adamantyl usually raise the glass transition temperature (T g) of a polymer by preventing the chains from sliding past each other easily. Short alkyl pendant groups may lower the T g by a lubricant effect.

  7. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also

  9. Saturate, aromatic, resin and asphaltene - Wikipedia

    en.wikipedia.org/wiki/Saturate,_Aromatic,_Resin...

    The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons . Aromatics, which contain one or more aromatic rings, are slightly more polarizable. The remaining two fractions, resins and asphaltenes, have polar substituents. The distinction between the two is that asphaltenes are insoluble in ...
