Abstract
The results of modifying high-density polyethylene (HDPE) by introducing thermoplastic elastomers (TPEs) and organobentonite (OB) are presented. An investigation has been made of the influence of the amount and the methods of introduction of a styrene–ethylene–butylene–styrene thermoplastic elastomer, including a maleinised thermoplastic elastomer (SEBS-M), and OB on the physicomechanical properties of the polymeric material obtained. The effect of modifiers on the impact strength of specimens, determined by the free-falling-weight method, is analysed in detail. It is shown that this method is the most informative for determining the effectiveness of modifying HDPE with thermoplastic elastomers and organobentonite.
