The Influence of Polyvinylpyrrolidone as a Polymer Modifier on the Morphology and Properties of Copolyamide
Peculiarities of copolyimide modification by polyvinylpyrrolidone in a viscous state were studied. The differential scanning calometry revealed changes in the morphology and phase transitions of modified copolyamide materials. The increased technological compatibility between the components of copolyamide-polyvinyl pyrrolidone mixture was established. The effect of the modifier on the strength and thermophysical properties of the studied thermoplastic was found. Introduction of polyvinylpyrrolidone contributes to the growth of copolyamide strength under rupture and relative elongation and leads to a certain decrease in Vicat softening point and change of copolyamide technological properties.
期刊介绍：
Materials Science reports on current research into such problems as cracking, fatigue and fracture, especially in active environments as well as corrosion and anticorrosion protection of structural metallic and polymer materials, and the development of new materials.
