Chapter 8, Problem 8.63PAE

Interpretation Introduction

Interpretation:

The polymers are classified according to their molecular forces.

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 have intermediary intermolecular attractions between elastomers and fibres.

Thermosetting polymers are cross-linked polymers which have different characteristics than thermoplastics.
