Phase-Transformations Of Polyamide Dispersed With Chromium Hexaaquachloride

The phase structure of compositions based on polyamide PA-610 and chromium(III) hexaaquachloride was studied by DTA, TG, DCS, electron microscopy, and X-ray diffraction. Mechanical action on the PA-[Cr(H2O)6]Cl3 System leads to the formation of a product of the polymer-salt interaction. The product emerges as a separate phase at the PA-filler interface. The glass transition temperature and the composition of the compound are determined. A structural formula and a mechanism of the product formation and growth are proposed.
