โœฆ Synopsis

The solution properties of copoly(4-vinylpyridine-4-vinylpyridine acetic acid) have been investigated by u.v., i.r. spectroscopy and viscometry. The molecular characteristics of copolymer at various ionic strengths were determined from the relations of Mark-Houwink-Kuhn and Stockmayer-Fixman. There is a strong influence of ionic strength on the hydrodynamic dimensions of the polymer coils. It is assumed that the conformation of macromolecule in the presence of low-molecularweight ions is controlled by a balance of intramolecular forces.

The compound Zn(Vpy)2CI2, where Vpy is 4-vinylpyridine, has been isolated from ethanolic solution after the reaction of zinc chloride with 4-vinylpyridine. Polymerization of this monomeric compound to [Zn(Vpy)2C12L was achieved. Also, poly(4-vinylpyridine) was reacted with zinc chloride to produce t
