Abstract

It was established by X-ray diffractometry that swelling agents caused a γ → α transition in chromium coordinated polyamides. This structural memory effect can well be interpreted by the formation of the mixed complex, [Cr(COamide)n(H2O)6-n]3+ proposed previously. The structure controlling the increase in the melt viscosity corresponds to n ≥ 2 while a treatment with a swelling agent (e.g. water) results in a complex structure of n {reversed tilde equals} 1 by ligand exchange. The latter involves a destruction of the partly crosslinked structure conferring the possibility of the structural memory.
