polymeric amide
Noun: A polymeric amide is a polymer containing repeated amide groups (-CONH-) as an integral part of its main chain. These materials are characterized by their high strength, thermal stability, and resistance to wear and chemicals.
The term "polymeric amide" is used in chemistry and materials science to classify a family of synthetic polymers. It is often synonymous with the more common term nylon, though it can refer more broadly to any polymer where amide linkages connect the monomer units. * Nylon-6,6 is a well-known polymeric amide. * The fiber's durability is due to its structure as a polymeric amide.
- The new textile is made from a high-performance polymeric amide.
- Researchers are developing a biodegradable polymeric amide for medical sutures.
- The mechanical properties of this polymeric amide make it suitable for automotive parts.
- Engineering polymeric amides: This refers to high-grade nylons used in demanding mechanical applications, such as in gears or bearings, due to their excellent fatigue resistance and low friction.
- Polyamide (n): The more common and technically precise synonym for "polymeric amide."
- Nylon (n): A specific type of aliphatic polyamide, often used as a generic term for polymeric amides in consumer contexts (e.g., nylon stockings, nylon rope).
- Aramid (n): A subclass of polymeric amides (aromatic polyamides) known for exceptional heat resistance and strength, used in products like Kevlar®.
- Polyamide
- Nylon (in common, non-technical usage)
The term "polymeric amide" has a single, specific technical meaning in polymer chemistry. It does not have common idiomatic or figurative uses. Its meaning is distinct from other polymers like polyesters or polyurethanes, which are formed from different chemical linkages.
