The polarization of polyvinyl alcohol films has been investigated. 
It has been established that it is a consequence of the breakdown 
of the cluster of intermolecular hydrogen bonds in the polyvinyl alcohol-water 
system. The critical indices of the breakdown process from the viewpoint 
of the phase, percolation, and fractal approximations have been found.
