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 having intermediary intermolecular attractions between elastomers and fibres. Thermosetting polymers are cross-linked polymers which has having different characteristics than thermoplastics.

Question

• Density: In both solids and liquids, the molecules are held very closely together and therefore their densities are about the same. In gases, there is space between the molecules. • Molecular movement and order: The molecules in solids are arranged in a regular pattern that does not allow for diffusion, although does allow for vibrations. The arrangement of molecules in a liquid, although not completely random, is not completely fixed. Molecules in a gas are randomly arranged and move very quickly. Gases diffuse quickly in comparison to liquids. Compressibility and thermal expansion: Since the molecules in solids and liquids are already very close together, applying pressure does not greatly affect the volume. In contrast, the space between gas molecules allows for a great deal of compressibility. Although temperature changes will cause slight variations in the volume of a solid or liquid, those variations are negligible compared to the thermal expansion of a gas. Shape and…

Chapter 8, Problem 8.64PAE

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 having intermediary intermolecular attractions between elastomers and fibres.

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