Hydrophilic Interpolymer Associates as a Satellite Product of Reactions of Formation of Interpolymer Complexes

It is shown, that reaction between polyacrylic acid and polyvinyl caprolactam leads to formation of wide range of different products. Besides classic interpolymer complexes and physically cross-linked hydrogels, the intermediates are formed. Those intermediates, particularly, include hydrophilic interpolymer associates, i.e. semistable polymer networks existing in dynamical mode, which is characterized by continuous process of formation/destroying of hydrogen bonds. Other intermediate products are relatively stable fragments of the polymer networks or associates stabilized by hydrogen bonds.
