✦ Synopsis

By irradiating dilute aqueous solutions of poly(vinyl alcohol) with t~sec-pulses of fast electrons, side-group macroradicals are formed and they are deactivated by combination and disproportionation. During the disproportionation, ---C(H)~---C(OH)---groups are formed in the main chain; they enable at low pH the formation of the rather long living ionic intermediate (III) with a strong optical absorption in the u.v.:

An investigation of influence of cryogenic treatment on extremely dilute aqueous solution of poly(vinyl alcohol) (PVA) was performed by viscometry. The solution was frozen in liquid nitrogen or in a freezer at 025ЊC, then thawed at ambient temperature and concentrated by evacuation. The viscosity of

The miscibility of poly(viny1 alcohol) (PVA) and poly(styrenesu1fonic acid) (PSSA) in dilute aqueous solutions was studied by a viscosimetric method. At a constant molecular weight of PSSA, it was found that the miscibility of both polymers increases with the molecular weight and the number of aceta
