Molecular structure, hydrostability and stabilization of polyurethane acetals

The effect of the nature and ratio of initial comonomers, the method of synthesis, hydrolysis level and the stabilizer type on the molecular-mass parameters of nonisocyanate polyurethane acetals (PUA) has been studied. The nature of active centres of polymerization has been suggested. The course of...

Description
Summary:The effect of the nature and ratio of initial comonomers, the method of synthesis, hydrolysis level and the stabilizer type on the molecular-mass parameters of nonisocyanate polyurethane acetals (PUA) has been studied. The nature of active centres of polymerization has been suggested. The course of hydrolytic degradation of various PUAs has been investigated. It has been shown that the hydrostability of PUA can be increased by salt additives.
