Dimers with Amide Linkages

Compounds 222 (R=Me, Et) containing five-atom amide replacements have been prepared and incorporated into oligomers, as have others containing the related piperazine-type linkages (see Vol. 29, p. 293-4). Other extended carbamate and urea-linked dimers, with a seven-atom link, have also been reported. ... [Pg.297]

The most common form of nylon, nylon-6,6, is made by polycondensation of the two monomers hexamethylene diamine (HMD) and adipic acid (ADA). The first step in the reaction sequence is the condensation of two monomers to form a dimer with an amide linkage, —CONH—, and a water molecule (the condensate). [Pg.89]

The Emser Industries process has no ester linkage, the bonds between the two segments being amides. An amine-terminated soft bis(3-aminopropyl)polyoxytetramethylene glycol is reacted with a dimer acid (Empol 1010) and caprolactum to form polyetheramide (PETA). [Pg.110]
