Synthetic polyamide TYPES OF POLYAMIDES Polyamides break down into three different families — aliphatic, semi-aromatic and aromatic polyamides, also known as aramids. Examples for polyamides that occur naturally are proteins, such as wool and silk. Polyamides contain the amide linkage group, and are typically made from a diamine Polyamides can also be formed from amino acids, which contain both the amine group ($-NH_ {2}$) and a carboxyl group ($-COOH$). Aliphatic Polyamides: These include This is part of the HSC Chemistry course under the topic Polymers.

Among the Here, we report a class of easily processable polyamides with stereocontrolled mechanical properties and high-fidelity shape memory behaviour. Polyamides are classified into two main categories: aliphatic and aromatic polyamides, each with specific characteristics and applications. The A polyamide is a polymer with repeating units linked by amide bonds. Nylon 6 and Nylon Polyamides, polyesters, and polypeptides are all examples of condensation polymers. Natural polyamides like silk are biodegradable, while synthetic ones like nylon resist breakdown and have higher strength. Examples of naturally occurring polyamides are proteins, such as wool and silk. In contrast, other polyamides, like Kevlar, have more complex structures that provide exceptional strength and rigidity. Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium polyaspartate.
