Abstract: 

The structure of the composite material of polypropylene - silicon nanoxide obtained by the method of mixing in the melt was investigated. The results showed that nano-SiO2 was little agglomerated and evenly distributed. Superdispersed SiO2 dispersed in polypropylene was found to affect the structure of the condensed polypropylene substance, which increases the crystallinity of polypropylene and leads to a decrease in crystal deformation. The distribution of crystalline particles was more compact, which proves that nano-organic solids can simultaneously reinforce and harden the polymer.
