Characteristics of Polymers
Amolecule has a group of atoms which have strong bonds among themselves but relatively weak bonds to
adjacent molecules. Examples of small molecules are water (H
O), methanol (CH
OH), carbon dioxide,
and so on. Polymers contain thousands tomillions of atoms in amoleculewhich is large; they are also called
macromolecules. Polymers are prepared by joining a large number of small molecules called monomers.
Polymers can be thought of as big buildings, and monomers as the bricks that go into them.
