New water-soluble poly(ether-amide)s (PEA)s were synthesised by polyco
ndensation of diethyl L-tartrate and commercial polyethers having isop
ropylamino end-groups (Jeffamine ED-600 or Jeffamine ED-900). PEAs wer
e derivatised with the synthetic auxin 1-naphthylacetic acid (NAA). It
was shown that PEA and their esters with NAA (PEA-NAA) form interpoly
mer complexes with polyacids and that the complex formation is favoure
d by the hydrophobic NAA-residues in PEA-NAA. The hydrolysis of PEA-NA
A was found to proceed mainly by cleavage of the ester bonds linking t
he pendant NAA-residues. The poly(ether-amide) main chain was found to
be more stable than the similar poly(ether-ester) chain of poly[oxyta
rtaroyloxypoly(oxyethylene)].
