According to the results of X-ray and complex thermogravimetric analyses, we establish the influence of nucleation agents based on polyvinylpyrrolidone and sodium liquid glass on the morphology of polypropylene. It is shown that the introduction of nucleation agents increases the degree of crystallinity of polypropylene and promotes a decrease in the sizes of crystallites. In this case, the most pronounced effect is exerted by the nucleation agent based on the codeposited polyvinylpyrrolidone and sodium liquid glass. It is also established that the changes in the structure of the material lead to the improvement of its physicomechanical and thermal properties, in particular, of the tensile strength, surface hardness, Vicat heat resistance, and Shram–Tsibrovsky high-temperature strength.

聚乙烯吡咯烷酮改性硅酸盐成核剂对聚丙烯形貌和性能的影响

根据X射线和复合热重分析的结果，我们建立了基于聚乙烯吡咯烷酮和钠液态玻璃的成核剂对聚丙烯形貌的影响。结果表明，成核剂的引入提高了聚丙烯的结晶度并促进了晶粒尺寸的减小。在这种情况下，基于共沉积的聚乙烯吡咯烷酮和钠液态玻璃的成核剂发挥了最显着的效果。还确定材料结构的变化导致其物理机械和热性能的改善，特别是拉伸强度、表面硬度、维卡耐热性和 Shram-Tsibrovsky 高温强度。
