*The influence of bentonite and pectin as PVC fillers taken in the amount up to 10% is considered on thermal stability, processability, strength, elasticity and surface properties of PVC films obtained by rolling used as a simplified model of calendering. The effect of heat treatment on the films colour was estimated when colour was used as a parameter indicating the degree of degradation by mechanism of formation of sequences of polyconjugated double bonds. To solve the problem of suitability of bentonite and pectin as fillers optical methods of investigation, thermomechanical analysis, thermogravimetry, DSC were used. Recommendations on application of bentonite and pectin in PVC formulations were given.
The production of polymer composite materials based on acrylic gels and such inorganic fillers as bentonite and detonation nanodiamonds, which make it possible to improve physical and mechanical characteristics of gels, was studied. Oscillation rheometry methods were used to study the rheological properties of these materials, based on the dependences of dynamic modules on frequency. The influence of the fillers studied on the values of dynamic modules and the tangent of the mechanical loss angle of the gel was discussed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
