Methoxylated polyamide and polyamide membranes
Journal of Polymer Science: Polymer Letters Edition, 1975Recent correlations of membrane polymer structures with desalting properties in hyperfiltration experiments have demonstrated the high desalting performance of polyimide membranes (1). Membranes were synthesized which were suitable for seawater desalination with a salt rejection of about 99.7% at 100 atm and at a feed solution of 0.6 M NaCl.

Miscibility of polyamide-6,6 with aromatic polyamides
Polymer Bulletin, 1996The polyamides with aromatic rings in the main chain were synthesized by the solution polymerization of 4,4′-diphenylmethane diisocyanate and aliphatic dicarboxylic acid in the presence of catalyst. The thermal properties and the miscibility behaviours with polyamide-6,6 of these aromatic polyamides were studied.

Polyamides (PAs) are high‐molecular‐weight materials containing amide units; the hydrocarbon segments between the amide groups can be aliphatic, partially aromatic, or wholly aromatic. We begin the chapter with an introductory section, and then discuss structure‐property relationships. Next, we present an overview of chemistry and analytical techniques,

POLYAMIDE RESINS ARE POLYCONDENSATION products of dimerized fatty acids and polyamines. Reactive liquid polyamide resins are oligomers designed primarily for use in the manufacture of two-component epoxy/polyamide coatings and adhesives. The two-component coatings are generally labeled Part A and Part B, with the liquid polyamide resin usually (though ...
