Polyamide - an overview ScienceDirect Topic

Polyamide. Polyamide (PA) is a polymer, which contains recurring amide groups (R—CO—NH—R') as integral parts of the main polymer chain. From: Advances in Textile Biotechnology, 2010 Related terms Polyamide, any polymer (substance composed of long, multiple-unit molecules) in which the repeating units in the molecular chain are linked together by amide groups. Amide groups have the general chemical formula CO-NH. They may be produced by the interaction of an amine (NH2) group and a carboxy

As nouns the difference between polymer and polyamide is that polymer is (organic chemistry) a long or larger molecule consisting of a chain or network of many repeating units, formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization, the joining of many monomer molecules while polyamide is.. Polyamideimide (PAI) Properties. Polyamideimides (PAIs) are high performance amorphous engineering thermoplastics of yellow to brown color. They have outstanding thermal, mechanical, and chemical properties and are often the best choice for demanding applications where very high mechanical strength, stiffness and low friction in combination with high temperature, corrosion, and wear resistance. The polymer known as nylon 6,6 takes the form of a salt, and when this salt is heated, it becomes molten. Once a polyamide fabric manufacturer has obtained this molten material, it is passed through a metal spinneret with a process called extrusion

Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® and VESTAMID® E (Evonik Industries).It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).The general chemical structure is Výroba. Polyamidové vlákno vynalezl Američan Wallace Carothers v roce 1928, komerční výroba byla zahájena v roce 1938 (pod označením nylon 66 u firmy DuPont).Přibližně ve stejnou dobu se začalo v Německu s pokusnou výrobou polyamidu 6. Mimo těchto nejznámějších druhů bylo ve druhé polovině 20. století vyvinuto nejméně 30 variant polyamidových vláken Polyamid se často využívá jako příměs do různých typů látek. Skvěle doplňuje vlnu v kabátech i svetrech, dodává pružnost bavlně v tričkách a halenkách. Spolu s hedvábím vytvoří základ jemnému spodnímu prádlu. Vzhledem k pevnosti a pružnosti vlákna se využívá také jako materiál pro sportovní tašky a.

  1. Major industrial polymers - Major industrial polymers - Polyamides: A polyamide is a polymer that contains recurring amide groups (R―CO―NH―R′) as integral parts of the main polymer chain. Synthetic polyamides are produced by a condensaton reaction between monomers, in which the linkage of the molecules occurs through the formation of the amide groups
  2. Another important polyamide is Nylon 6,12. It is less hydrophilic than Nylons 6,6 and 6 due to the larger number of methylene groups in the polymer backbone. For this reason, it has better moisture resistance, dimensional stability, and electrical properties, but the degree of crystallinity, the melting point and the mechanical properties are.
