Definition of polyamide in English:



  • A synthetic polymer of a type made by the linkage of an amino group of one molecule and a carboxylic acid group of another, including many synthetic fibers such as nylon.

    ‘Generically known as a group of polyamides, nylon is chemically distinguished by its amide linkages to two aromatic rings.’
    • ‘One polymer that is widely used for extruded balloon catheters is polyamide (nylon).’
    • ‘Examples of polymers produced in this way include polyesters, polyamides, polyurethanes, polyethers, and polysulfones.’
    • ‘Nylon 66 is a polyamide based on hexamethylene diamine and adipic acid.’
    • ‘This molecular weight is relatively low and not far from the critical molecular weight of polyamides, which is generally near 15,000 g/mole.’
