POLYMERS
,Polymer chemistry is part
larger discipline of materials
which involves the creation
materials to replace metals
ceramics, fabrics, wood, ca
and paper.
, Classification of Polymers
Classified in different types on different basis
Classification on basis of source: Classified into three types
a) Natural polymers:
• obtained from plants or animals
• e.g. cellulose, silk, wool, leather, natural rubber, leather, DN
lichen etc.
b) Semisynthetic polymers
• The polymers obtained by simple treatment of natural fi
improve their physical properties like lustrous nature,
strength
• E.g acetate rayon, cup ammonium silk, viscous rayon
