Phase transitions and physical states investigation of the cryoprotective systems based on 1,2-propanediol and polyvinylpyrrolidone by the DSC method.

Number: pap. ID: 887

Author(s) : BYELYAYEVA I., ZINCHENKO A.

Summary

Complex cryoprotective system based on 1,2-propanediol with polyvinylpyrrolidone as a high-molecular additives was investigated. By the differential scanning calorimetry method the regularities of the noncrystalline inclusions, non-equilibrium crystallization and melting were studied in this system at a ratio of the concentrations of 1,2-propanediol and polyvinylpyrrolidone 1:1, 2: 1, 4:1. The values of the phase-transition temperature and glass transition temperatures were obtained.
