The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
Well in polymerization or in dehydration synthesis, the individual monomer molecules contain either H or OH attached to the end of their respective molecules. When they chemically compline together both the H and OH come off or break from their respective molecules and form water as a product. In place, a covalent bond is produced connecting the monomers together. In break down of polymers, with Water, the water molecule essentially disconnects the large molecule at the same place where it would have formed a covalent bond, and causes one of the monomers to bond to either a H and or OH. Separating the 2 compounds.
