hydrogen bond

A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom, especially a nitrogen, oxygen, or fluorine atom, usually of another molecule.

hydrogen bond

(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules

hy′drogen bond`

an electrostatic bond between a hydrogen atom in a covalent bond and an electronegative atom, as oxygen.

hydrogen bond

A chemical bond in which a hydrogen atom that is already bonded to an atom in a molecule forms a second bond with another atom, either in the same molecule or in a different one. The second atom is usually of a type that strongly attracts electrons, such as nitrogen or oxygen.

As can be clearly observed in Table 1, the [f.sub.H.B] value of TBP is higher than that of other polyurethanes, indicating that TBP synthesized by half of coplanar and symmetric 2,6-TDI (50 wt% in TDI) forms much stronger hydrogen bond. Strong intersegmental hydrogen bonding between two adjacent MDI-based hard segments in MBP would then be unlikely, because two aromatic rings on the central methylene unit of an MDI are neither coplanar nor linear [25].
