Abstract

Compositions based on bentonite and acrylic copolymers were obtained. The dependence and improvement of the thermal characteristics of polymer compositions was also observed in the study of materials based on poly (styrene-co-acrylamide) with bentonite clay of Navbakhor Deposit. The use of bentonites as fillers significantly increased the thermal properties of the resulting composites and to reduce their combustibility, which allows them to be used as slow-burning materials. That bentonite-filled composites are more thermally stable than unfilled copolymers. The use of various types of clays as polymer matrix modifiers allows us to solve a range of tasks from increasing the deformation-strength characteristics to obtaining materials of a given geometric shape, which leads to the creation of a whole assortment of new “intelligent” polymer composite materials. In addition to giving the polymer matrix improved strength characteristics, it is necessary that the composites retain their sorption properties, therefore, one of the types of fillers that are used are bentonites. This allows you to immediately unambiguously determine the nature of the processes in the substance, which is impossible to do only according to DTA or other thermodynamic methods. Research of polymer composite materials in work it was carried out on the derivatograph STD Q600 with a temperature range of -25 ־ 500°C and the rate of temperature rise - 5°C/min.
