Abstract
The paper is focused on the experimental investigation of the montmorillonite nanofillers effect on deformation properties of polystyrene KRASTEN 171. The combination of a low amount of clay with dispersed polymeric phase may cause synergistic effects leading to very fair balance of mechanical behaviour in some cases. The paper analyses the effect of nanocomposites and type of the material on the individual measured parameters, relations between them, strength and deformation behaviour. Deformations were evaluated by non-contact videoextensometry method. The results show that doping of the base material polystyrene with nanofillers particles has an effect on the plastic deformation increments.

Summary
The aim of this paper is determination of the effect of montmorillonite nanofillers on mechanical properties of polystyrene KRASTEN 171 evaluated by a non-contact videoextensometry method, which provides new results from tensile tests. Videoextensometry is a non-contact method for strain measuring, which enables the scanning of both longitudinal and transverse strain components from the surface of the test specimen [1, 2]. After specimen scanning the evaluation of the strain components will be completed and final results from co-ordinates of gravity centre of individual dots will be calculated by used SW [4]. This method enables the scanning of the deformation in two directions by one camera system [5, 6] and deformation kinetics development is recorded during videoextensometry measuring
