The interaction of poly(ethylene glycol) with some salts of alkali‐earth metals (Mg(ClO 4 ) 2 , BaCl 2 , SrCl 2 , SrBr 2 and CaCl 2 ) in methanolic solutions was investigated by electroconductivity, viscometry, X‐ray diffractometry and NMR. It was established that the conformation of macromolecules is strongly changed in the presence of Mg(ClO 4 ) 2 . Chlorides and bromides of alkali‐earth metals have a weak influence on macromolecule size. The formation of amorphous complexes in the PEG–Mg(ClO 4 ) 2 system and crystalline complexes in PEG–chloride systems of alkali‐earth metals was shown.
