Chapter 8, Problem 8.64PAE
Interpretation Introduction
Interpretation:
The
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.
