Thermoplastic Vulcanizates Filled with а Layered Silicate

Abstract:

Oil-resistant and thermoformed thermoplastic vulcanizates based on butadiene-nitrile rubber and polypropylene were obtained, containing a layered silicate montmorillonite as a filler. The structural characteristics of composites based on thermoplastic vulcanizates were studied using the methods of fractal analysis. It has been established that the value of the static flexibility of the polymer chain of a thermoplastic vulcanizate containing montmorillonite exceeds the static flexibility of the polymer chain of an unfilled thermoplastic vulcanizate. It is shown that the introduction of montmorillonite in the amount of 1-3 pbw in thermoplastic vulcanizates leads to improved performance characteristics of the obtained composites.
