The increasing order of intermolecular forces in different polymers is elastomers \( < \) plastics \( < \) fibres. So, in order to solve such problem, first classify the given polymer into the above classes and then arrange them in increasing order of forces. Neoprene (synthetic rubber) is an elastomer, buna-S is also an elastomer, polythene is plastic and nylon-6, 6 is a fibre. So, the increasing order of intermolecular forces of the given polymer is : Neoprene \( < \) buna-S \( < \) polythene\( < \text { nylon-6, } 6\)

Fibres have the characteristic features like
1 Thread forming solids
2 High tensile strength and high modulus
3 Crystalline nature
4 All of the above
Explanation:
Fibres are basically thread forming solids which possess high tensile strength and high modulus. This is due to the strong intermolecular forces like Hydrogen bonding. These strong forces also lead to close packing of chains and hence impart crystalline structure. E.g., terylene, Nylon-6,6 etc.
