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
