摘要

研究了聚乙烯吡咯烷酮在粘性状态下对共聚亚胺进行改性的特殊性。差示扫描量热仪显示了改性共聚多酰胺材料形态和相变的变化。共聚酰胺-聚乙烯吡咯烷酮混合物各组分之间的技术兼容性得到了提高。还发现了改性剂对所研究的热塑性塑料的强度和热物理性能的影响。聚乙烯吡咯烷酮的引入有助于提高共聚酰胺的断裂强度和相对伸长率，并导致维卡软化点的一定程度降低和共聚酰胺技术特性的改变。

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.
