Concept explainers

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.

Question

Write an equation for the formation of the following polymers.
(a) Polystyrene, from styrene (C6H5CH=CH2
)
(b) PET (polyethylene terephthalate), from ethylene glycol and terephthalic acid

Definition Definition Large and very high-molecular-weight substances that consist of hundreds to thousands of repeating units. Polymers are also known as macromolecules. Number-average-molecular weight is the measuring system for the polymers.
