Abstract
Influence of unmodified and dimethylsilylated nanosilicas on rheological characteristics and structure formation on melt flow of polypropylene–copolyamide blends was studied using differential thermal analysis, viscometry, and optical microscopy with statistical treatment of the microstructure data. Nanosilica has an influence on the parameters of melting and crystallization of polymer blend extrudates. Modified nanosilica with grafted dimethylsilyl groups is a more effective additive on fiber formation than unmodified nanosilica because of a stronger affinity to polypropylene. Optimal compositions of the polymer blends and optimal extrusion conditions of production of filled polypropylene microfibers were determined. It was shown that addition of nanosilicas to the polypropylene–copolyamide blends is an effective method to control the formation of microfibers.
