Polymers

Polymers are naturally occurring or synthetically produced large molecules or compounds which are made up of series of repeating units called monomers. They are joined together by chemical bonds. The term polymer is coined from Greek roots meaning 'many parts' and are found almost everywhere from the plastics bags to the rubber of our tires to our DNA strands.
