Concept introduction:
The polymers are classified based on the intermolecular forces present in the compound. These are four types. i.e., 1) Elastomers 2) Fibres 3) Thermoplastic polymers 4) Thermosetting polymers
Elastomers are the polymers which contain weakest forces of attractions.
Fibres are the thread forming polymers which contain very strong intermolecular attractions. Hence these polymers are used to make ropes (nylon (6, 6))
Thermoplastics are the polymers which are linear or slightly branched and having intermediary intermolecular attractions between elastomers and fibres.

Some important notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
