Abstract
Polymer matrix, filler and composites based on low-density polyethylene and flue ash microspheres were studied using IR spectroscopy, DSC and TG, as well as the data on combustion heat. It was demonstrated that the introduction of microspheres into the polyethylene matrix leads to the change of structure as a result of an increase in the degree of polymer crystallinity, and to the formation of new chemical bonds, decrease in melting point and heat of combustion of the composites, an increase in the temperature of the start of intense thermal destruction.
