Polymers can be classified on the basis of molecular forces like vander waals forces, hydrogen bonds & dipole dipole interactions.They are classified as :
 
1 elastomers- they have elastic character & have weak intermolecular forces.Eg natural rubber
 
2 Fibres- thay have strong hydrogen bond or dipole dipole interactions between polymers chain.Eg nylon 66
 
3 Thermoplastics- they have intermolecular forces intermediate between elastomers & fibres.Eg polythene
 
4 Thermosetting polymers- they undergoes permanent change on heating.Eg bakelite
 
(i) Buna − S
 
(ii) Neoprene
