Abstract:

In this paper we have examined the rheological properties of spinning solutions of polyimideamide (PIA) nanocomposite containing different amounts of montmorillonite (MMT) in the form of the Nanomer PGW (produced in the USA), modified with aminododecane acid with octadecylamine. It has been found that regardless of the content and type of MMT, the solutions of PIA-MMT nanocomposite in N-methylopyrrolidone are non-Newtonian fluids rarefied by shearing without flow limit. The rheological properties of PIA nanocomposite spinning solutions depend not only on the content of MMT, but also on the type of its modifier.
