PLASTIC MATERIALS
TIME LINE
In 1828 Berzelius coined the word "polymer", making a distinction between two compounds
of the same composition, but of different molecular weight. It was to be more than a century
before the extent of the "polymerisation" was realised and the subsequent developments of
the theory of the structure of polymers earned Staudinger a Nobel prize in 1953. By this
time, the polymer industries, rubber and plastics, had grown to international proportions and
today's major materials already introduced.
