Polyamides

Assertion (A) Polyamides are best used fas fibres because of high tensile strength. Reason (R ) Strong intermolecular foces (like hydrogen bonding within polyamides) lead to close packing of chains and increase the crystalline character hence , provide high tensile strength to polymers

The condensation polymer are those which gives out some simple molecules like H_(2)O in course of reaction. Mostly in this reaction functional group changes. Polyamide is
