Abstract
The topochemistry of the process of suspension alkoholysis of vinyl polyacetate has been studied. It was thus demonstrated that the alkoholysis occurs in three stages: the first takes place in the homogeneous phase, the second in the gel phase, and in the third sineresis takes place a process that leads to forming a numerous pores within the polyvinyl alkohol pearls fact demonstrated by SEM. This study made possible to propose a mechanism, through which the pores are formed as well as the dependence of pearl porosity on the concentration of initial vinyl polyacetate solutions subjected to alkoholysis. Keywords: alkoholysis, polyvinylacetate, polyvinylalcohol
