Abstract
The technology of nanocomposites based on polyamide-6 (PA-6) and modified montmorillonite is developed. The technological parameters of extrusion and injection molding, and their influence on the formation of nanoscale inorganic phase of the polyamide are investigated. Morphology and thermal behavior of polyamide-6, composites based on PA-6 and modified montmorillonite are studied by WAXS, XRD, DTA and DSC data. New γ-phase formation is revealed in composite polyamide-6 – 1 – 2% of modified montmorillonite. Optimal concentrations of modified montmorillonite in the composites stated as 1 – 2% are shown to correspond with composites improved properties as compared to initial polyamide-6. It is explained by increasing crystallinity degree, which resulted from acting of modified montmorillonite particles as nucleation heterogenetic agents.
