The results of the studies of influence of polyvinylpyrrolidone on the kinetics of formation and the growth of Freon-12 gas hydrate are presented. Based on the P-V-T measurements the degree of conversion of ice into gas hydrate at various concentrations of polyvinylpyrrolidone was calculated. The fact of preservation of inhi-biting properties of polyvinylpyrrolidone in formation of a gas hydrate based on frozen aqueous solutions has been established. The studied polymer shows promoting properties, which leads to an increase in rate of the growth of Freon-12 hydrate based on modified ice.
