Classification of Polymers
Classification of polymers
(1) Classification lies on source of availability : They are divided as
(i) Natural polymers (ii) Synthetic polymers (iii) Semi-synthetic polymers
(2) Classification based upon structure : On the basis of structure of polymers these can be classified as
(i) Linear polymers (ii) Branched chain polymers (iii) Cross linked polymers
(3) Classification lied upon molecular forces : Depending upon the intermolecular forces, the polymers have been classified into four type.
(i) Elastomers (ii) Fibres
(iii) Thermoplastics (iv) Thermosetting polymers
(4) Classification lied upon mode of synthesis : They are of two kinds on the basis of their synthesis.
(i) Addition polymers (ii) Condensation polymers
(5) Classification based upon the nature of monomer : On the basis of behavior of monomer. Polymer are of two kinds
(i) Homopolymers (ii) Copolymers
