Like many substances, polymers were discovered by
accident
In 1933 in Cheshire two chemists were working for ICI
trying to make special chemicals
They heated large amount of ethene overnight
In the morning they discovered a solid, waxy substance at
the bottom of their reaction vessel ­ this was the first
polymer, polythene
Now almost every substance around you is made if a
polymer
A monomer is…read more
