O Monomers
O Homo polymers
O Copolymers
O Difference between Homo Polymers and
Copolymers
O Molecular Weight
3. Definition-Polymer
O The word polymer is derived from
classical Greek poly meaning “many” and
meres meaning “parts.”
O A polymer is defined as a macromolecule
formed by the repeated combination of
several simple molecules (Monomers)
through covalent bonds”.
4. Definition-Polymer
O The polymers are defined as
macromolecules composed of one or
more chemical units (monomers) that are
repeated throughout a chain (Covalent
bonds).
O Polymer - "many parts" (poly = many).
O A polymer is a high molecular mass
compound ranging from 5000 to one
million.
5. Definition-Polymer
O The modern understanding of polymers as
macromolecules was proposed by
Hermann Staudinger in 1920.
O Example: - polyethylene monomer is
ethylene, which is repeated x times along
throughout the chain.
